You're laughing but when I worked on a search engine, it was a serious question which videos should we display if the search query is just "BBC".
The prudent approach prevailed for a hundred different reasons but online user metrics weren't one of them. Apparently people were not very fond of the British Broadcasting Corporation, especially outside of the angloshpere.
Why would it be? I can't think of a single meaning of BBC which translates to an insult. GIMP on the other hand has more than one meanings as an insult (not even an acronym).
Definitely came after the original BBC being established, and definitely is orders of magnitude less known than the sexual slang variant. So yeah, the Gimp comparison doesn't stand, at all.
Describing one’s … favourite desert? (HN is American so not sure we can say the word here) doesn’t constitute an insult - people say it all the time irl. But you’re also right that BBC wouldn’t be a good name for a design tool either.
Naming things is hard, someone should setup a focus group :)
