This.
What makes it worse:
- Each "bad" term gets replaced by multiple alternative terms, often non-obvious, so good luck figuring out what people mean now. For example, MitM (Man in the Middle) was a well established technical term. Everybody knew what was meant, the term had no acutal gender association in the meaning, but now you instead read "machine-in-the-middle, meddler-in-the-middle, manipulator-in-the-middle, person-in-the-middle (PITM), or adversary-in-the-middle (AITM)".
- The "it's more descriptive" excuse was used as a very thin veil of justification even though the actual reason for the change was clear. So not only do you get to deal with the extra hundreds of hours of overhead, but you also have people lie to your face about why you're being forced to do that.
- It never ends. First it was "master/slave", then "master" in any context, and once that battle was "won", proponents of such policies started finding new "offensive" words.
