I'm confused. The article states that the monthly feed is to remove ad targeting, which I assume means no ads. It does NOT say that they won't collect data on you, just literally that they won't use the data they collect to give you ads.
So this has nothing to do with opting out of data collection, just opting out of ads? That's the feeling I get from the article.
Edit. Well I guess I'm not confused, this is also the wording the Meta's post uses and definitely says nothing about opting out of data collection.
