It doesn't matter if you post anything to Facebook, or if you even have Facebook account. Almost every commercial site in the world has a "Share this" button somewhere that is loaded directly from Facebook. IF you have a Facebook cookie, your information across the Internet is collected. IF you block Facebook cookies, but use somewhat static IP, you are still monitored.
Google and every other company that lives by datamining users for advertising purposes tries tier best to do the same. Aggressive adblocking in your browser helps a bit, at least you can tell your browser to not send the request, but it's VERY HARD to stay outside the data collection from these companies and adblockers are a constantly escalating war of attrition.
The End Boss isn't Meta, Google or Twitter.
It is advertising networks and the entire advertising industry.
