Redhat is not pushing developers into producing software incompatible with anything but their own system. They are actively involved in the development of almost all core software common to all distros, and even flatpak, which is meant to tear down barriers between distro package formats rather than prop up the wall.
Microsoft could push Windows all they want if they were not also pushing an ecosystem exclusive to that platform along with it. If Windows was "just another unix" and was interchangeable at the user level with other operating systems, particularly those that would respect user freedoms, there would be no issue with its nature as "default" or in Microsofts behavior in regards to its users, because there would be real choice.
Real choice, in exactly the same way Red Hat vs SUSE vs Ubuntu users have right now amongst themselves.
Oh... ok. So because Redhat makes some products that ONLY work on Linux, and are interchangeable between a few distros (although not the supported paid-for versions), you get "real choice".
What's my choice if I'm an AIX user, or a Solaris user, or an HPUX user, or a Windows user, or a FreeBSD user? My choice is to switch operating systems? Sort of like the choice MS provides?
