Is he though? Even if he is, didn't he deserve it more than any other billionaire. Linux is FOSS after all and changed the world and IT dramatically. The money from Linux isn't in his hand, but in the hands of Linux Foundation as far as I know. Linus didn't make much money from Linux. Otherwise where is the evidence for this claim? I'm not against any evidence, I'm just against spreading false information. Also he does a lot still and maintains the project with lot of other people.

Many people, including myself, are very unhappy with his decisions, like the removal of several Russian developers from kernel maintainership status.

Ah, its about that. So anything else is not the real reason, its about the politics. I don't know if this is justified or not, as I don't know much about this situation.

Reading further its also the person is unhappy that C++ is not in the Kernel (but Rust got). I'm glad that people take matters in their own hand and fork if they are unhappy (regardless of any reason), but what is the point of this fork other than just being a fork? I wish that person or group good luck.
