Not sure what more you need; it is no secret that kernel code is written primarily by and for the benefit of corporate entities, and naturally they have priorities.

[I am not saying this as a bad thing; in fact, the GPL licenses are designed around this "fact of life" aiming to maximize the benefit for (all) the users and minimize control of a single powerful entity. I'd say the current state of affairs is amazing, considering the historical alternatives.]

It seems like a reasonable complaint, but a subset of

"Your bug is neither a regression nor a severe issue."

Since the paid developers, just like literally everyone else who contributes, do fix the most serious bugs in their areas of expertise/responsibility, but triage some reports as not the most valuable use of their time, or, if applicable, their company's resources.

Large companies hire people to work on open source. Some use their clout to influence standards.

As a developer I like that companies hire for open source. As a user the quality increases with full time employees. What we don't notice is many projects morph to fit corporate needs because they become important stakeholders.

Money and power corrupt by design.
