what's your take on employers banning the use of languages other than English between coworkers at the workplace?

Racist, and a way for management to know if workers are discussing unionization.
Not always, it’s also a politeness thing, it depends on context
I don’t agree. Forcing people to use a language they are less comfortable with just so others can eavesdrop has nothing to do with “politeness.”
I think you should have asked what context was being referred to.
I can’t really imagine a context where it would be a politeness thing unless the English-only speaker was actively involved in the conversation but was being intentionally shut-out, and not because it was easier to convey in non-English languages but deliberately for spite.

I can’t really imagine a context except for this very common context which completely negates my point

Well said!

It isn’t the context brought up in the post body, so no, it doesn’t completely negate my point. The post is talking about banning any and all use of spanish, period, and the other user came in trying to talk about a different situation entirely.
