I remember when IBM, SGI, Infornix, Oracle, and HP first got involved in Linux. At the time, I included patches from some of them in the Functionally Overloaded Linux Kernel.
I proposed, back then, a simple league table for commercial support of Linux: Every new major feature or software product got so many points, and every bugfix release got a smaller number of points. Kernel features that made it into the mainstream kernel would qualify as goals for, kernel features and products discontinued were goals against. Closed-source contributions got half points, and were also considered goals against.
It would then be obvious which companies were serious and which were piggybacking, and it would also be clear who understood the philosophy, not just the opportunity.
Such a table would have ensured that nobody forgot the companies who contributed. Quite the opposite. There'd be an incentive to encourage the team you supported to improve position in the table.
Of course, no such league table ever happened. I could have maintained such a table without difficulty, but it would require the vendors to openly say what they'd contributed. I couldn't invent one out of thin air.
So I'd say Oracle has to look at themselves, not just the Linux community.
It's possible to conjecture - we know it collided with something massive, so if said body contained very limited radioactive materials, one might expect this to reduce the radioactivity per unit mass.
Is this the answer? Probably not, but it's good enough (I think) to argue that a simple answer is possible.
It has never worked in any empire, it has never worked in any software development team, it has never worked in any rock or metal band. I see very very little reason for saying there "should" be a power struggle, that always ends badly with no exceptions in any domain. C++ has never been in the kernel, so it's hard to see how Rust could defeat it there. Rust is unlikely to replace C because they do different things well - if the Linux devs have half the intelligence they seem to, there will be a natural federation.
And that is the key concept. Linux is, by its very nature, a federated OS kernel, many teams working in their territory but cooperating with other teams working in other territories through a central "government" that happens to have a hereditary god as head of the state machine.
