"Leaving *diffusive* information is no problem at all"
You clearly haven't listened to Eben Moglen's speech I linked to. Please do so. He discussed that very issue, referring to it as the "...data dandruff of life which people don't think of as special in any way but which aggregates to things that people would be very creeped out to think could exist." (Or something along those lines.)
"Why don't you demand that the forum should be hostet in a decentralized way, scattered over the servers of many trisquel users? That's the whole point of my argumentation: you reject one service but you obviously don't realize that other things you do on a daily basis are basically the same thing."
Because I've been talking of Telegram. Please don't be confused though that my discussions of one thing don't mean I don't expect the same in other areas.
"The owner of telegram servers can track my meta data on conversations with a few people. If i use google services, google knows 1) what I'm searching on the internet 2) my email conversations 3) what videos I watch 4) maybe even what products I buy etc."
Yes, and this is problematic too. Please spend some time to listen to that talk.
