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?
The web UI would be the safest bet I think.
Apps may have their own mechanisms for loading links to news articles, videos and stuff to make it show in a user-friendly way, with the downside that the linked website can respond with a tracking image as the Opengraph banner etc.
