Why did people start talking about open source in this thread? This is almost the opposite of open source, and doesn't claim to be open source. It's restrictive to the point where you should just treat it as an official source leak. It's even called "collaborative" by which they clearly mean that if you want to work on the software, you're free to send them a pull request. You're also free to compile it yourself, as long as you don't distribute it (modified or not) in any way.

Nothing wrong with this, but I don't understand why people started arguing about open source. Because you get to look at the source?
