I very much doubt anyone is actually offended by the word "motherboard". More likely it's a dumb inductive argument. "Some people are offended by some gendered words => every gendered word might offend someone => every gendered word must be eliminated as a precaution".

The exact same pattern was leveraged against blacklist - a word that has absolutely no connection with the skin color usage. It has been removed by notable projects and people were up in arms talking about it being necessary due to "people being offended".

Motherboard. It took me a few moments to guess as to why this is a "problem". Obviously due to the word mother. Let me roll my eyes.

Frankly it is completely absurd to be offended about a word that is part of a process that keeps our very species existing. Sadly I would not be surprised at all if there are google employees who are offended on behalf of "people being offended".

This is basically a semantic debate, but I guess this all is anyway. I don't disagree with the pattern you are describing, but I would describe it a slightly different way. There are people getting offended on the behalf of other people who potentially might get offended. Even if this second group never materializes or doesn't even exist, that first group is still getting offended on their behalf.

Basically I don't believe that "precaution" you mention is an apathetic but cautious person. These changes are more often motivated by someone who thinks "this might offend someone so I will take offense to it too".

There will be a group offended by anything.

People are wild. You can find small groups of people who do and think insane things. We as a society should not try to cater to every possible sensibility. That's a recipe for disaster.
