Almost everyone in ecom is running every ad network integration they can, no matter the source of traffic.
So if you click a Facebook ad, load a website, enter your information/checkout ALL of your information goes to every other network they integrate with.
You might never use TikTok, you might have every Facebook domain blacklisted, but when you clicked on a Google search "result" (ad) and checked out everything about your order was sent to meta/tiktok/applovin/400 other "networks" via S2S APIs.
Until this is made illegal, the incentive structure will ALWAYS push marketing departments to do this.
You think the census is what the government would use to mass identify and imprison people, not the NSA database(s)?
You think homeland security, or the FBI, or any other alphabet agency doesn't already have access to a giant list of people?
Think about what meta knows about everyone, or Google. You do realize that the US gov has read access to their core databases right?
"The census" has absolutely no bearing on any of that which you're worried about.
It's just shocking the level of ignorance that gets upvoted in the comments here now.
