Indeed. Though I wonder how many of the “big tech profits from open source and doesn’t pay the maintainers” complaints are from actual maintainers vs. observers with a general axe to grind against big tech.

Sure, at least some of it is from observers: I am one of them. But... Are there any rules against that? If something's true, then is it any more or less true depending on who you are or what you do?

You don't ignore complaints from systems you use for work. This isn't at all a political issue for engineers.
