I may be in the minority, but I make a distinction between personal IRL information like searching my name reveals my phone number or address. And online tracking information like when I have this cookie or browse from this IP, show me more X. Also Facebook is a large responsible company (no major data breaches, etc.) I know they're hated on, but something like Equifax is several orders of magnitude worse in my opinion.
Facebook (and maybe Google?) buy data about me to try to match me online so they can provide ads on their own service, but they don't reveal my data to anyone else - advertisers don't get my phone number or physical address or even email from them, when they want to advertise to me.
The companies that optery seems to be fighting against are ones that post my physical address and phone number and family members and name online in one spot so anyone can find it, without me ever opting in to that.
