This happens exactly because there is no competition and hence antitrust is needed. I don't want to be using services from Google/Facebook/Microsoft but there's no competition and then I end up using their services even when trying to avoid it as most as possible...
If the prices for services would go up without surveillance capitalism so be it, that's the real price, I want to choose to pay for it, not be coerced into giving them my data for their "free" services. I don't have that option right now, nor anyone else, why are you against freedom of choice?
