Any idea what this is about? I doubt Proton has that many trackers, so I was thinking maybe the individual emails? But those would just be triggering when I click on links, which I thought Proton stripped anyways, and I wouldn’t think /e/os would attribute those to Proton either.
Ah yeah I completely forgot about “magic pixels” and image based trackers. I was just considering special links. That make sense. Still I do recall hearing Proton saying they block those things, but maybe /e/os doesn’t realise they are being blocked somehow.
