I own a startup that focuses on E-Learning and EdTech. we have a portal that uses moodle to teach students. We charge a small fee for each courses when people enroll, Now the site is fully re-branded with our custom css and we have a few inhouse plugins we wrote. I was wondering if we could do the same for a mobile app. I looked into docs about it, Moodle Offers a re-branding of app for a price of US $3000/year while still the source is open. I have people in my company who has the skills to take up that source and build a completely rebranded app, now my question is, is it legal to do so? The source states its Apache 2.0 license which implies that it is legal until I segregate the changes I've made, if thats the case then does all features of moodle mobile comes with that source? Can I use that source, reskin it, add some more plugins and still do a commercial business out of it? I am confused about it because if only rebranding and building the app is the case I think $3000 is a little expensive(atleast in my country ). So I just want to make sure what's going on.
PS: by stating its expensive, I never mean to offend the Moodle guys. They are doing a great job by keeping moodle open.
