Will not speak about future, but about the past. As external observer for about a couple decades I would second that. I always praised RedHat for meticulous following GPL. They are required to make available source of their derivative work. They do more, as rpms are more than just source. To my folks I maintain machines for as sysadmin I always mention as example cygwin. After RedHat bought out Cygnus Solutions, they kept cygwin alive, available and active project. BTW, cygwin was the first where guest system calls were on the fly colverted to host system calls. Which makes virtualization really fast. Compared to emulating generic CPU what vmware was doing at that time. No one mentions that, but proprietary parallels desktop is doing the same, having learned it from cygwin, and VMware later followed the same route I bet. Of course, one can only guess about proprietary software.

Not happy about CentOS change, but where credit is due, I can not avoid mentioning it.
