Likely, you will see a bunch of random ads instead of targeted ones of things that might actually be interesting to you. Whether or not that's better is up to the user.

I had the realization a while back that certain advertisers were flooding my Newsfeed with Sponsored posts every time I interacted with them in some way -- on or off Facebook. So I started regularly clearing out the Interests and Advertisers sections of Ad Preferences and now my Newsfeed is almost entirely devoid of Sponsored posts.

The experience using Facebook without them exploiting knowledge of my "preferences" is substantially better.

Granted, I'm running ad blockers, so most of the low-value advertising on FB was already blocked.

Indeed. I've discovered it can make major mistakes on who's "important" to me - I'd thought they'd stopped Facebooking, but it turned out their algorithm had for some reason deemed them not to be a "close" friend and de-emphasized them from my feed.

He meant 'my Facebook won't be as profitable'.

I agree this probably won't make Facebook as good. I relate this to the time before spam filters were good and 50% of my email was penis enlargement pills and money wire fraud. You dump all this data and we go back to a time where I'm not known, and Facebook shows me my active "friends" and it's just my aunt sharing her latest Bejeweled score.

I'm all for better control of my data, but there needs to be some balance so the ads I see are still relevant and not acai berries super juices and Hot Local Singles In My Area.

It won't have that "tailored experience".

People can pin this on Facebook all day, but that's the same bullshit every user-productizing company spews. That the best experience is the one they design, which necessarily includes tracking, ads, and half of the dark patterns in the book.

It's a veiled threat, just like when they told you that if you disable facial recognition you're worsening the experience of blind users, and that nefarious people will take your photos and impersonate you.

I read that sentence as you can try to get rid of us, but we'll be back!

They probably intentionally selected things to delete to cripple the experience. It's a way of forcing people bad-mouthing facebook to put their money where their mouth is. If critics don't use this feature, they can put the blame solely on them.

The sentence should be rendered as: "Your Facebook won't be as good [for us] while it relearns your preferences."
