Every company has its detractors, all you can ask yourself is if you agree with the companies actions and if you are proud of your involvement.
Red Hats support of various things isn't alturisim, businesses do things because its in their interest. Red Hat funds things like systemd, gtk, otk, etc.. because it means they can set the technical direction, it reduces development costs, its part of a montisation plan, etc..
This is why its making its changes, it doesn't think CentOS feeds into RHEL licence purchases and the open source builds were to support RHEL clones.
So Red Hat could just stop supporting all those bits but it should seriously hurt Red Hat (if it doesn't there is a question on why Red Hat is doing it).
