I realised, that sometimes it is more like a different experience level. And some people forget it could be possible the asking person is an absolute newbie.
And most people in forums are there because they want to help, but they want to help on this one asked case and won't teach the whole Linux universe, most people need years of experience for.
The good thing is, we can use AI for this nowadays, it won't go mad if you are missing an elemental "you really should know, how this works" kind of error.
