Facebook has my age and home town, knows what many of my interests are via groups I'm in. I don't think it's wrong to say I have given them that information voluntarily and so long as they keep it on their servers only, I'm ok with them showing me a mountainbike ad because I'm a 40yo male who is in a mountainbiking facebook group.
I don't consent to them showing me an ad for a specific mountainbike that I placed in the shoppingbasket at cheap-mountanibikes dot com last week, and then abandoned there, and the reason they know is because the store has some kind of arrangement of any kind with facebook. That's the kind of thing I don't think I should even be allowed to consent to.
Instagram in comparison sends me a ton of personalized ads and I actually really like them. I have a modified .ipa of instagram (Rocket for iOS) and while it turns ads off I actually have that setting changed so I still see ads. Sometimes I find things I really like.
Why not?
I’m asking why you think that it’s a net negative that you’re able to consent to that.
