Red Hat is Novell in 2010s.

Compare: both had deals with Microsoft,
both try to take control over Linux, controversial decisions of both
were and still are highly criticised in the community, both are companies
developing enterprise solutions. Let's see what Red Hat controls:
rpm, GNOME, NetworkManager, SELinux, systemd, CentOS
is now their acquisition. I reckon I am still missing something. 
Also don't forget contracts with various vendors.
