It appears Microsoft are happy to keep designing products with the intention of wasting peoples time (again). Not very efficient and defo sounds like a future lawsuit in the making.
If the pop ups were even remotely useful, or disappeared automatically after a time, it's unlikely there'd be complaints. Unfortunately, I have found them to remain until they're cleared away and being completely irrelevant my business user Teams needs they've become very annoying (reminds me of the neighbours whining dog outside in the cold - the problem isn't the dog! - and there's not much I can do about it other than to raise a complaint). A simple disable button in the settings would be so easy to implement.
