@Sandra @kensanata I understood. I'm saying that indexing posts you make in public is an extremely different scale of privacy risk than the kind of tracking that ad/tech/social companies do.
On fedi, the tracking is limited to what you share on fedi unless your host is malicious/compromised. You know exactly what it's possible to track, and you can exercise control of it fairly easily: your posts and your profile and your fedi network. Mainstream networks track a huge percentage of your activity even away from those networks, even if you don't have an account, and it's not always possible to know what they know about you
It's "nosy neighbors" vs "secret police" levels of privacy risk.
