If yes then that's an unreasonable standard to hold people to.
If no then I can't figure out what your comment means.
"This is a problem, and here is what I/we should do", takes a bit more effort.
Firefox is still open source last I checked. You can still contribute, write bugs, write letters to the CEO, etc...
I'm only taking issue with tendency people have to throw shade without offering a solution.
But it's really hard for a normal person to do much about steering firefox other than helping raise a fuss.
Sometimes there isn't "a solution".
If you don't have something to contribute (like a direction, suggestion, correction), then as they used to say, you are "part of the problem".
And even if it's useless that doesn't make it FUD.
