Yes, that's absolutely what happened.

The problem is, by doing that in a platform of Google's size, they have effectively declared themselves the arbiters of what is inappropriate.

I suppose all copy editing features do the same, but being the arbiter of spelling is easier, since spelling isn't morally charged and you can just go with Merriam-Webster for US English.

And I suppose if they were to use that power to flag old slurs, including those people might not know, especially for non-native speakers, great, they might catch some embarrassing errors.

Instead they decided "landlord" is bad word, for some reason, and now I will make fun of them.
