For those reading the comments first and getting confused as I did: This is not about a NewPipe developer getting their Google account suspended due of a ToS violation (which would already be a disproportionate sanction, considering the practical consequences of the suspension). It's a NewPipe user getting their account suspended. It's like loosing access to your Google account because you dared use an ad blocker.

And NewPipe doesn't even link to the Google account, so it's not clear how Google made the connection.
