That is not comparable because the stuff written with GPT is known to have a far higher probability of being extra wordy with bullshit that wastes people’s time

That is not comparable because the stuff written with GPT is known to have a far higher probability of being extra wordy with bullshit that wastes people’s time. If a friend uses GPT to generate an initial draft and then edits it or at least checks it, it is not any different. But if they are using GPT to save themselves time at the expense of your time, then it is an issue. I can even envision a future where you get paid by advertisers for inserting product placement into your chats with your friends, at which point I would call them “friends”, and not friends.
