Your choices aren't between tracking and subscription, they're between tracking, subscription, and advertisement. You can advertise without tracking (contextually, the original claim of AdWords) and you can sell tracking data to non-advertisers. To say that the economic model of the internet depends on privacy violation is a "the world has to be this bad" argument that just doesn't hold up, especially given the memory of internet advertisements in the time before so much brainpower was funneled in to tracking us.
