I've asked a couple of questions I'd hope would be fairly simple (like how to run a program in cgroups v2), set a big bounty on them, and never got a single useful answer.
I recently asked a question about Java and Maven development differences in VS Code between Windows and Mac OS and got only one answer from someone who didn't actually read the question. So, yeah, it sure seems that way.
Like Yahoo answers? It's probably tough to get the incentives balanced. Without a really good design you'll get lots of people without deep knowledge answering many questions and playing the numbers game.
