As a non-native speaker, I agree. Such tools are not new and extremely helpful when writing professional documents.

I also think that we are nowhere close to actually censoring words in editors like Google Docs, MS Word, ... even though it might seem like a small change from providing suggestions to enforcing them. But when you think about it, it's a huge change, both from a technical standpoint and even more so from an ethical one.

Providing writing suggestions is certainly far from the worst thing that tech monopolies have ever done.
