First, Fedora is not Red Hat but their own community. (Although heavily sponsored by Red Hat) Second, Red Hat is FOSS.
The ones hostile to FOSS are all the freeloading companies, which used the work of Red Hat to increase their own profit, w/o contributing anything back.
If it is so easy, cheap and so much fun to support a stable Distribution for 10 years with backports for security vulnerabilities and drivers, I am very surprised that we don’t have hundreads of community distributions which do this.
Finally, over the years Red Hat contributed a load of the things we take for granted now.
(Writing this as a happy Debian user. I am just tired of reading this kind of bullshit again and again and again.)
