But the bottom line is that tech like this, that gives them the minimum they need without extra, is a hard prerequisite to any such laws even being genuinely considered. It’s easy to disable, and doesn’t give any extra information on default use case users because of all the other tracking. Advanced users who block that can block this easily. There’s no real downside.
There’s no legitimately plausible path to just banning their data collection without allowing for attribution of transactions. It won’t happen.
Banning them in the US or the EU would have a huge impact, because it would preclude businesses that operate in those countries legitimately from participating in the market for those countries. But it isn’t something that’s going to happen.
