Theme 1 – Privacy‑invasion concerns
Many commenters view fingerprinting as a creepy breach of personal privacy.
“My reaction to this is always two fold; firstly cool tech, secondly horrifying invasion of privacy.” – 1a527dd5
“If every website you ever visits knows it is you, exactly what links you clicked on, and what content you viewed, forever, are you truly ok with that?” – floorsthelimit
Theme 2 – Technical effectiveness and possible mitigations
Discussion centers on how well fingerprinting works and what users can do to reduce it (browser tweaks, randomization, etc.).
“Wow, that is a seriously impressive demo. I wonder how it’s able to distinguish people using identical hardware and software versions…” – snazz
“The ideal result you should aim for is ‘non‑unique fingerprint’. That means your device is indistinguishable from countless others.” – nvme0n1p1
“I've been obfuscating my fingerprint with Brave for years…” – eks391
Theme 3 – Cookies, state‑keeping, and the regulatory focus on tracking
Cookies are seen as a legitimate tool for maintaining web state; the real problem is the tracking they enable, which regulations (e.g., EU consent rules) target.
“Cookies, in and of themselves, are not bad. Like any tool that can be misused, they're just being abused by a ton of really shitty people…” – blooalien
“This is already illegal in the EU. The consent banners were never about cookies, they have always been about the tracking itself!” – crote
