RedHat is probably the biggest Linux contributor across the whole ecosystem
They contribute more to the advertisement and sales industry than to the kernel. The point is the efficiency of the money spent on them for the open source ecosystem. If you think that on $4 given to redhat only $1 should go to the devs then we have a fundamental disagreement.
I did pay money for their subscription, I already had to deal with them. I won't do it anymore, I prefer to give my money to the people doing the hard work. But you've already said before that the "reactions are overblown" and they decision makes sense. So your opinion was already made anyway.
