In my experience, nobody has any problem with you sharing your knowledge with them if (1) you’re an actual expert (and not just an “armchair expert”, (2) they actually want or need someone to tell them the information they’re looking for, and (3) you express it courteously and kindly.
In pretty much any case, you’re not likely to ever get good results if #2 isn’t true. Maybe they want to figure it out themselves. Maybe they don’t actually care. Maybe they’re making a joke that people who really are experts would get!
Even if you don’t have #1, you can get a long way with #3 (especially if you frame it as you’re a fellow learner sharing what you’ve gleaned so far, such as by giving them info and asking for something in return—“oh, I found out that you can do X and it works really well, but I could never figure out Y, how’d you do that?!”).
