alt Hacker NewsI'll post some inside baseball:
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.

It is made illegal. As the post notes, you need to (1) give notice and (2) data collected needs to be made available in a user access request and (3) deleted irrevocably on request. You must have a legitimate reason to process and store this data (scattershot forwarding to everyone is a prima facie violation). Unless you comply with all of these, you are in violation.
I'm already low-consumption, but my personal boycott of any site using shopify, which straight up has all integrations in their js you can inspect, has lowered my consumption even further. I've been emailing stores asking them to switch to bigcommerce, or whatever, and stop sharing their customers' data. Never get answers, though I never expect any.
