To be clear: I prefer to pay for things instead of having to see ads but 13€ / month!? For a meta product that has inherently user-hostile design patterns even without ads?
They are still going to be tracking you. That isn't going away.
They just won't use the tracking for the explicit reason of creating ads for you. But that's only because you are paying for no ads.
I guarantee the data is logged for all other purposes, and that the data is logged for future ad usage if you ever unsubscribe.
Secondly this doesn't necessarily equate the profit from your specific ads. This is the result of a legal battle within the EU. That's the only reason it exists. The price is determined as 'high enough to not get into more legal trouble'.
Meta already demonstrably does this. I deleted my real Facebook in like 2016. Around 2019-2020, I created a new burner account to browse Marketplace with nearly all fake info expect my name, phone, and email. And lo and behold all of my friend suggestions are people I know and mostly were on the old account. The most charitable I can imagine is that those suggestion had me in their contacts which they agree to share with Facebook (which is problematic af imo) but it is extremely likely they just retain all of data especially since many of the people I was suggested have never had my current number/email.
You deleted your real Facebook account... but did you delete the anonymous shadow account...?
It's not that Facebook hasn't deleted the data from your real account, it's that they keep tons of "anonymous" shadow accounts, each one of us probably has a dozen of them from different interactions with Facebook, and your new account most likely got suggestions from getting paired with those.
There is this neat horrifying thing the Facebook app does by tracking your location and figuring out where you work in order to suggest colleagues you can add as well as I have noticed just tracking if you happen to be near another device with a unique account on it.
The huge swath of very intimate data they are collecting on us is so not ok and they have all kinds of creepy stuff they don't even admit too.
From me? Of course not. Unfortunately, I do live in society and do have to share my contact info with others, and I'm guessing the vast majority of people just spam the "okay" button as Facebook asks for contact access, mic access, camera access, access to your colon, etc.
I also think this subscription model has run into criticism from EU legislators/regulators as well, which will have to be decided upon. Basically Meta isn't out of the doghouse yet.
Really, I'd say strip Meta of all its assets and dissolve the whole thing, maybe try some of the heads for all the shit they've pulled in the ICC? Like failing to act on genocides or actively working to incite mass violence, political unrest, etcetera.
Oh the data will absolutely be used for ads elsewhere. It's just how the ad game works. It's all interconnected. I also don't think it's inherently bad, it's just what it is. It's how targeted ads work. They will be stopping that. They just also won't have to buy data themselves about you because they're not showing you ads anymore.
I think this is much more likely what they think people will pay. And/or what they think a percentage of people will pay that will cover costs/lost revenue from other users leaving. They have basically zero incentive to make it a 1-to-1 replacement.
