I’m not sure why everyone keeps repeating this. The fight is lost. Your data is being collected by the websites you visit and handed to Facebook via a proxy container. You will never see a different domain, it’s invisible to the end user.

Care to elaborate on the mechanisms at play? If what you claim is true, all websites would already serve ads from their own domain. The main issue I can see with this approach is that there would be an obvious incentive for webmasters to vastly overstate ad impressions to generate revenue.
Look up Facebook Conversions API Gateway
As far as I understand, the objective is completely different. Ads are shown on platforms owned by Meta, and the Conversions API runs on the merchant's website (server-side), and reports interactions such as purchases back to Facebook.
This is quite different from websites monetizing traffic through and trackers placed on their own webpages. Those can still be reliably blocked by preventing websites from loading third party content.
