PM-ME-YOUR-HANDBRA

Wait, so you're saying that an app built by a world-class comedian and his depressed Canadian "friend" that's seemingly hastily assembled and being guerrilla marketed on Reddit just in time to capitalize on COVID-induced isolation isn't AAA-Grade software? Color me surprised.

To clarify, he's saying they use the canvas element for those features, not that they're using canvas fingerprinting for those features.

I don't know what browser plugin /u/gunch was using for this, but it's very likely it just warns about all uses of the canvas element and is not necessarily capable of determining whether a site is doing actual fingerprinting.

Edit: from his linked Wikipedia article:

However, Tor Browser is currently unable to distinguish between legitimate uses of the canvas element and fingerprinting efforts, so its warning cannot be taken as proof of a website's intent to identify and track its visitors.

As a software engineer: that "backtracking" statement basically means "Fine we'll just deprecate it for V3 and then when Manifest V4 rolls around it'll be disabled completely and we can say 'we just removed a deprecated behavior'."

As it turns out, apes are pretty good at aping people's actions.
