A non-ad subscriber won't get shown ads, but that definitely doesn't mean Meta can't profile and collect data to sell to other ad companies so you would still get targeted ads on other websites. They just won't get shown ads on Facebook.

Facebook doesn't sell data. They sell access to data. I'm not trying to be pedantic, but it's important because it's meaningfully different.

Facebook doesn't sell data to other ad companies because that'd be giving away the very thing that makes it the most valuable advertising company in the world. Hell, we spend a huge amount on facebook, and it's impossible for us to get reports on basic things like "Spend per placement per hour".

The only area that I could see them _maybe_ still monetizing an opt'ed out user is with Meta Audience Network, but I bet they would still opt them out of seeing ads on 3rd party sites that have MAN ads in their stack because that business segment is likely small compared to potential PR and fines in the EU.

That is an important distinction to make, though what it might look like (even if MAN is also opted out) could be that the users don't see ads, but they are still possibly contributing data to the overall ad profile business. The data would be used for less targeted stuff like demographics or similar wide brushes, since the individual user it came from isn't part of the feedback loop by seeing targeted ads anymore.

I guess I'm saying even if they aren't targeting an individual with that individuals data, they can use it to target other individuals who do see the ads.
