Friendica, само программное обеспечение, оно не подлежит обмену. Matomo используется добровольно только в некоторых случаях. https://github.com/friendica/friendica/issues/9316

I just registered an account and it seems to me that friendica is trade-free. However the browser extensions Privacy Badger and uBlock Origin go a bit crazy, but that must be because of the content and the external links posted in the feed. I also found out with uBlock Origin, that friendica uses Matamo which is a powerful web analytics platform.
