Today I installed the Raccoon for Lemmy app. The app itself does not contain trackers or extra permissions.
However, after I clicked on the icon of the installed application, my firewall immediately showed the presence of the appbrain.com tracker.
In other applications for Lemmy, the firewall also displayed many blocked trackers.
I may be wrong since I am not a programmer, but I think that the trackers are loaded along with links to external news sites.
Is it really impossible to come up with protective mechanisms that would prevent trackers from leaking into Lemmy?
There are no calls to appbrain.com from lemmy.today. Chances are your own system is compromised.
For the purity of the experiment, I reinstalled the browser again and the first site I visited was a Mastodon instanse https://social.tchncs.de/
There are no trackers.
