[Cerowrt-devel] [Make-wifi-fast] wireguard almost takes a bullet

the 'control' that the various companies gain over parts of the kernel is less a
matter of the company having control and more a matter of them hiring/sponsoring
a developer who has the control. If the person leaves that company for another
one, any control moves with that developer.
and while most of the developers do work for a reltively small group of
companies, the list of developers does shift over time nd people can 'break in'
by submitting patches.
I'm not thrilled by the Linux Foundation, it was created to be a way to pay
Linus without him working for a specific company (avoiding even the appearance
of bias) but it's morphed to present at least the appearance of special access.

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).

> 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.

> 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).

> 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").
