Whaaaat? I thought so many lives were improved by making devteams replace all usages of "black/whitelist" with "block/allowlist". Well, except for the lives of the users, on-call engineers, 1st and 2nd level tech support, the product owners, and everyone else who had to deal with sudden, unexpected, hard to track bugs resulting from such BS changes. Oh, ofc I apologise for my use of the word "list", which may be hist…
As a non-American, the dumbest change that affects me daily, is the renaming of the master branch. Master means teacher in romance languages and its variations are part of daily usage. In git there's no "slave" part so it always meant "main" and not "owner" It affects me daily because "look on master" became "look on the main branch" for no advantage to absolutely anyone.
(I do support the master-main change in git for other reasons tho: it's much easier to translate and more natural to say. "Master record" is a term that never got translated into many languages, or at least not in a way that still makes sense for git)
