But then aren't they themselves contributing to projects like Fedora and adding value to it in return ? I don't know anything but it seems that they are also contributing to the ecosystem. Plus it's not like we lacked free quality linux distros, do we ? If you feel like you are being taken adavantage of, what prevents you to contribute to say Debian instead ? I am learning programming and most students like me runnning linux don't run RHEL or CentOs and and frankly barely even know acknowledge their existence.
