There's only so much information you can get with hardware though. No doubt the software in tracking fingerprints, and matching similar ones has become very sophisticated. However, I wouldn't be surprised if device fingerprints hasnt increased in diversity much.

On the other hand, maybe they're using a spectre/meltdown attack to get a MAC address or something. In that case, we're fucked.

In 2010, Electronic Frontier Foundation launched a website where visitors can test their browser fingerprint.[14] After collecting a sample of 470161 fingerprints, they measured at least 18.1 bits of entropy possible from browser fingerprinting,[15] but that was before the advancements of canvas fingerprinting, which claims to add another 5.7 bits.

If I'm understanding that correctly, that would give ~14.6 million unique fingerprints just based on your browser. That's a lot, but also tiny compared to the billions of Meta users. I'm a little skeptical that they would be able to determine a user is from the EU without using IP or cookies.

Edit: If they block users who's fingerprint matches an EU user, and their IP comes from a known VPN service, then they could likely get pretty good accuracy. I wonder if there are any North Americans getting blocked while using a VPN.

Sounds interesting. Do you have a source, or further reading for any of this?

Who's going to be paid for the ongoing maintenance of the software? Who's going to pay for the servers the software's run on? A decentralized architecture doesn't remove the operating costs of a large scale social media site. As the article alludes to, it might even increase operating costs.

To be honest, I'm not interested in small, niche communities. I want the fediverse to grow into something that can rival social media giants like Reddit, and Twitter. How a site is monetized is as key of a feature as anything else, because without monetization, a site is doomed.

So how is Kbin going to cover its operating costs? If a fediverse server must survive on donations, it seems like donating should be built into the user experience. For example, there could be a Kbin Gold similar to Reddit Gold.

I remember years ago when Reddit Gold first became a thing there was a progress bar on the site indicating how much of their daily server costs had been covered by Reddit Gold. Something like that might be useful.
