Google Classroom may indeed be one reason but what I’ve seen is many educators avoiding an LMS entirely. Zoom, email, Google Drive, Google Forms are the mishmash of tools they’ve cobbled together in the rush to get online. My daughter had to buy a new printer for my 8 year old grandson in New York City to print his assignments. My understanding is the parents were responsible for checking the work and reporting which has created a learning gap for the primarily, lower income families still working full time, with low bandwidth and in many cases no internet access at all.
We're still using Moodle and have a number of academic departments who prefer it to MS Teams. Overall our Moodle usage has increased but the vast majority of departments are now using MS Teams. Even those who are using Moodle use MS Teams for their live lessons.
When it comes to virtual learning all I hear from people outside of the Moodle community is talk of Microsoft Teams and Google Classroom. One of my friends who works with Google Classroom once said 'Don't you need a degree in computer science to run Moodle?'. I often feel I'm fighting a loosing battle trying to show how Moodle can do everything MS Teams and Google Classroom can do and so much more.
I think this may well be a case of Maslow's Law of the Instrument, i.e. When all you have is a hammer, it's tempting to treat everything as if it were a nail.
Most people, teachers included, are more or less comfortable with using MS Office. It's been around for nearly 30 years & it's been on school curricula & library learning aids & tutorials for at least a couple of decades. I think it'd be hard to find anyone who hasn't had to use it or even anyone who hasn't had some kind of instruction on using it.
What happened? There was a pandemic. Everyone had to go online to continue their classes. What was the easiest tool to use? The one they knew best that somehow did the job, one way or another: MS Office or something closely resembling it, e.g. Google Docs (renamed for education & a few extra GUIs & scripts added). I'm really not surprised at all that this is what has happened. I remember a number of pundits predicting it from the outset.
Familiarity with MS Office also meant that admins, teachers, students, & parents had a lot more knowledge & skills to work with from the outset & so MS Office/Google Docs enabled them to focus more on the learning content rather than the UI.
Yes, if we'd had time to prepare (any) LMS', courses, & resources in advance & train admins, teachers, students, & parents how to use them, we'd probably have better organised & collated resources & activities, & better learning outcomes than at present & everyone spending less time doing mindlessly repetitive & poorly organised admin tasks that LMS' typically automate.
And I very much doubt we'll be sufficiently prepared when/if the next pandemic strikes. Niccolo Machievelli wrote about how he was dismayed at how disinterested people were in preparing for predictable disasters, i.e. floods that occurred regularly, back in 1513. Things don't seem to have changed much since then. There have been realistic predictions from experts about coronavirus pandemics for at least the past decade & we've had plenty of experiences of pandemics in the past, enough to know that lock-downs are pretty much inevitable with highly contagious viruses: https://www.businessinsider.com/people-who-seemingly-predicted-the-coronavirus-pandemic-2020-3
Rolling out the edTech is relatively easy. The real challenge for online & distance education is building institutional & system wide capacity for being able to use LMS' & edTech tools effectively. I had a really easy time with getting Spanish students to use Moodle because most of them had used it at their schools & universities. Getting people in Canada used to using it is somewhat more of a challenge. I can't tell people about how distance education works & discuss options; I have to create mock-ups & give demonstrations for most people to even grasp the basics. I think we're still at the early 1990's stage of adoption, similar to when MS Office was still a strange, new, intriguing thing.

I use Teams every day - it's ok but it's hardly a game changer. I can never find anything and they can't even put a 'Reply' button in the right place. I'll not worry about my Moodle day job quite yet.
The main issue I have is that Teams doesn't have anywhere near the same feature set as Moodle does. All you get is assignments and quizzes along with a rudimentary gradebook. There's no interactivity with any of the resources created or uploaded to Teams. The fact that it's easier to use (in our teachers opinion) than Moodle is what is converting many of them.
The teachers who do use Moodle love the wide breadth of options available to them. They create badges for their courses, setup Wikis, and use Workshops, etc. and love how they can customise their own courses and structure its content.
This phenomena is also know as monopolizing. That's the main reason behind the "grilling" going on right now: https://www.bbc.com/news/technology-53592751. I wonder the US congress can change the cause of the NetThings. May be those Network Barons themselves are caught in the bow wash of some "higher" affairs.
Anyway, the good news is that a significant number went to Moodle, thanks to the prompt action of the consortium of Moodle Partners. Not anything comparable to what Microsoft and Google collected, but huge for a ecosphere based on the Open and Free Software principles.

That doesn't mean a great deal. Browsers are free (of financial purchase cost), but people have high expectations. A Walk in the park is free of direct purchase cost but we have high expectations (or at least I do).
The thing that is not free is the time of experts. Moodle is usable 'out of the box' but it doesn't get interesting until you add some plugins. That doesn't take a huge amount of expertise, but if you want to use it over the long term and upgrade it and integrate it with other systems then you start to need experienced people, and they expect to be paid.
If you give me a free set of expensive carpentry tools and some high quality wood and ask me to build a chair, you really would not want to sit on the result.
