I was pissed off in the beginning as well! Came out of nowhere, it is interesting that this is happening now and not before, but I guess the times are tougher today then they were years ago. If you look at RHELs financials, they are not doing that well it seems, maybe I misunderstood the information, but based on the earnings, they are not doing that great, so to an extent, I am not surprised, this just feels like they are trying to monetize more, which makes sense, if they have to have people supporting the distro internally, building new features, etc.. I think there should compensation, even if the open source world, we should contribute and support the folks putting in the effort.
I guess, it was all a matter of time...
