There have been proprietry packages available in Linux distros for ages.
As long as they are optional and you don't lose expected functionality if you choose not to take up that option, no problem.
I've as much time for these burgers telling me what I can and can''t do with my machine as I have with Mr Shuttleworth doing so.
No having can't from them or must from anyone else. Linux is about options, if there's only one, it's not linux.
