> why the hate against this small change?
Because it's not "this one small change", it's friction added everywhere where you're trying to communicate, while also implicitly (and sometime explicitly) being called evil for using well-established language.
It's also not 1-2 terms, people come up with new, increasigly far-fetched reason to ban new terms every year.
I'm trying to submit a patch, but instead I have to deal with a linter telling me that "blacklist" is evil, so I'm now supposed to either refactor the existing software or tell some vendor to please change their URLs.
I'm trying to understand something, but I now first have to guess what a term is supposed to mean, because each keyword with a well-established meaning has now been replaced with half a dozen of new terms.
I'm trying to push a git repo to Github and things break because different parts got updated to the politically-correct "main" instead of "master" at different times.
It's a no-win situation, either you just silently take it and put up with it - but that makes the problem worse, because people come up with more bullshit, or you push back. Either way you're stuck dealing with this, as you call it yourself, bullshit.
