The problem is that those issues have, and continue to, cause damage to the Linux project. Good maintainers have been hounded out, or simply given up, and bad blood exists where it absolutely shouldn’t. You’re right that much of it is political, although that usually stems from deep technical differences backed up by corporate encouragement. Political turmoil can be as damaging, if not moreso, than technical differences. At least technical differences can usually be resolved technically, politics is infinitely more nuanced.
From Marcan’s description, the way certain people treated him was absolutely unacceptable, although I’ve no doubt they’d describe things very differently. I hope the whole kernel team, maintainers and contributers, can find a way to work through these differences and work more harmoniously before more members end up burnt out, frustrated and bitter.
That just means that businesses aproaching that value get split into two, with the same owners, via the same sorts of shells and offshore trusts.
