Theodore -
I appreciate you showing the LF executive salary numbers are not quite as high as I noted. My numbers may have been inflated, but I've definitely seen a $900,000 package for at least one executive reported in the press (an executive who was transferred in from a F100 company which is close to the LF).
On the other hand, they are pretty damn high salaries for a non-profit. Are they appropriate? Depends. There are no stockholders and no profits, just a pretty substantial net worth.
Regarding the organizaton of "Linux, Inc." as  a hierachical control structure - I'll just point out that hierarchical control of the development of Linux suggests that it is not at all a "community project" (if it ever was). It's a product development organization with multiple levels of management.
Yet the developers are employees of a small number of major corporations. In this sense, it is like a "joint venture" among those companies.
To the extent that those companies gain (partial) control of the Linux kernel, as appears to be the case, I think Linux misrepresents itself as a "community project", and in particular, the actual users of the software may have little say in the direction development takes going forwards.
There's little safeguard, for example, against "senior management" biases in support of certain vendors, if other vendors are excluded from effective participation by one of many techniques. In other words, there's no way it can be a level playing field for innovation.
In that sense, the Linux kernel community has reached a point very much like Microsoft Windows development reached in 1990 or so. I note that date because at that point, Microsoft was challenged with a variety of anti-trust actions based on the fact that it used its Windows monopoly status to put competitors in the application space, and competitors producing innovative operating systems out of business (GO Computer Corporation being one example of many).
This troubles me. It may not trouble the developers who are in the Linux community and paid by the cartel of companies that control its direction.
I have no complaint about the technical competence of individual developers - the quality is pretty high, at least as good as those who worked on Windows and macOS. But it's becoming clear that their is a narrowing of control of an OS that has a lot of influence in a few hands. That those few hands don't work for one company doesn't eliminate its tendency to become a cartel. (one that is not transparent at all about functioning as such - preferring to give the impression that the kernel is developed by part-time voluntary "contributions").
The contrast with other open source communities is quite sharp now. There is little eleemosynary intent that can be detected any more. I think that is too bad, but things change.
This is just the personal opinion of someone who has been developing systems for 50+ years now. I'm kind of disappointed, but my opinion does not really matter much.
