Isn’t that a reason for people to be more helpful in helping others resolve their performance issues and to raise bug reports as appropriate?
No, see, that's my point. There's a whole family of bugs where people don't want to be told how to fix the bug themselves, they want the bug to never have happened in the first place. Or, you know, at best for it to be patched and removed without their intervention.
Showstopper bugs? Sure, those you just want a way to get past so you can do what you want to do, but experiential bugs, bugs that don't block you but make things slightly more annoying? For most people any additional effort in fixing the bug just makes the bug worse at that point. Especially if it's not an open-and-closed "just do this and it fixes it".
A slight performance degradation over time that clears up with a reset is not that big of a deal. Being walked through debugging processes I've already tried that won't actually fix the issue is an extra annoyance on top of having to deal with the bug. At best. At worst it feels patronizing, in that hey, I know what I'm doing, right? It's annoying in the way calling customer support and having to go through the dumb easy part of the script where they tell you to turn the thing off and on again is annoying. Except I didn't call customer service, I just complained about the bug and now people on the Internet are crawling out of their hideouts to do customer service at me.
So no, no every situation calls for trying to walk somebody mentioning a bug through basic QA processes. Software is supposed to just work, and for the average user, if you add homework on top of their software not working, that's just extra incentive to not use the software. OSS fans sometimes miss that small but relevant part of the user experience.
