I don't mind someone having my details, I just don't want that someone to be a party incentivized to spam me.
At the core of both of them is an economic transaction (direct dollars vs. ad impression), both of which use personal data like web history (to know which article has been "bought").
The big difference is the ad supported model is not linked to your bank account, and has some pseudonymous properties, but there is still the classic three-party structure of reader, publisher and platform, and still the huge pressure to be profitable.
1) So you're still having your personal web history tracked by a technology company, possibly even worse because it's linked to your bank
2) Economic pressures and incentives are roughly the same
3) End result is your data will eventually get sold anyway, much the same way that cable companies always introduced ads
I also have a belief but no hard data that advertisers pay more per impression than consumers ever will, which leads to this cycle happening in the first place. People seem to forget that the internet wasn't really profitable until targeted advertising, cutting that would mean the end of most web technology companies.
Pay one subscription, visit sites. If those sites have a specific meta tag, add-on detects it, providing you with access to paywalled articles. The longer the site keeps my attention, the more of my subscription they get. They don't have to know a single thing about me other than "I'm using this service and I have a running subscription". Service aggregates those micropayments from their subscribers within a time frame and avoids transferring small transactions and fees associated to the website.
Cheap. Private. Low-friction. Pick two.
