You seem really worked up over some perceived slight by people you'll never meet running some random website committed against you, personally, with intent.
You think they have contempt for you? "The feeling or attitude of regarding someone as inferior or worthless." "The state of being despised." That's a bit of a stretch.
There's nothing wrong with expecting people to do ~10 seconds of research to find out what an acronym means. It look me less time to open a tab, type "nvr video", wait for the HTTP request, scan the page, and close the tab than it did for me to write the last sentence of this comment.
