I use ProtonMail, and I was thinking, “Damn, it’s spectacular not being tracked… but hold on a minute. Perhaps less than gmail, but still at all. And what about browser fingerprinting, and cookies, and even fonts!” I ended up in that feedback loop we all end up in. Perhaps ignorance is bliss? What is something you (might) wish you were ignorant of?
They used to use your list of installed fonts as one of the data types to figure out who you are.
I’m not sure if that’s still a thing, how many people download new fonts now, but it was an important part of fingerprinting at one point.
