Why not? You can consent to having your audio recorded. They can even offer a higher “private” price and a lower “ad supported” price. I write “private” because I assume the microphones will always be listening no matter which price you pay.
I guess that's semantics. If you opt in then yes I guess they could do anything. I think the point was that enshitification would occur if they forced you to do that.
You could opt in to have blood or plasma taken on every ride if you so wanted I guess.
