I would guess that just getting a random problem to solve might not be appealing to all devs.
On the other hand, maybe some people are having problems that may have already a close-enough solution so that why would I want to build yet another one, or maybe some are so hard to implement or would require too much effort that they don't get any interest from devs.
Pretty often when I meet someone and tell them what I do for a living they start giving me all these ideas that I should be obviously doing because they are so great and no one has solved that before, or they ask me if I would know how to solve this 'simple' problem of theirs, only to have them be surprised when I tell them how much it would cost to develop an app that has offline-sync capabilities, social media features, stores pictures 'for free', etc so that they can manage their neighborhood gardens or their pottery class (hint: I'm not doing it for 500 dollars).
I'm guessing some of that could be happening here if the problems-to-solve are not curated by estimated development cost or by simplicity.
Of course, I'm not the OP so it's just a wild guess :)
