"Please don't pick the most provocative thing in an article or post to complain about in the thread. Find something interesting to respond to instead."
I don't feel like that rule works here? If you cut out part of the second sentence to get "Find something interesting to respond to", that's a good point, but the full context is "instead [of the most provocative thing in the article]" and that doesn't fit a complaint about acronyms.
To paraphrase McLuhan, you don't like that guideline? We got others:
"Please don't complain about tangential annoyances—e.g. article or website formats, name collisions, or back-button breakage. They're too common to be interesting."
The point, in any case, is to avoid off-topic indignation about tangential things, even annoying ones.
