I've not suggested anyone be 'barred' from commentary.

Rather, if you want to dump generic negativity on a real, delivering project, you should justify why your negativity is relevant, for example by documenting your own related efforts.

If you want your cynicism to be respected, then yes, that's a privilege that needs to be earned. You can always say it, but it should be called-out as empty bullshit until backed with detailed reasoning or experience.
