I think it is simply that we have very different views on what a discussion involves. To me it is all about asking questions, exchanging information and hopefully learning something. So, it doesn’t matter to me, on a public discussion forum, who provides the answer. You, on the other hand, often seem to want a discussion to be about point scoring, setting traps and trying to shame people. So, I can see that if somebody else joins in and actually provides the answer, that might wreck your little schemes. And if that is what you mean by "veiled trolling", I honestly couldn't care less.
