You might say "I don't need to be able to propose a solution in order to point out problems", and sure, but that's missing the point. Because by pointing out a problem, you are still implicitly asserting that some solution exists. And the counter to that is: no, no solution exists, and if you have no evidence in favor of your assertion that a solution exists, then I am allowed to counter with exactly as much evidence asserting that no solution exists.
Propose a solution if you want complaints to be taken seriously. More people pointing out the problems at this point contributes nothing; we all know everything is shit, what are you proposing we do about it?
