I didn’t really give a good explanation, here’s what the owner has to say.
It’s because the youtubers coming over only agreed for their content to be viewed on tilvid.com, not other instances so they owner follows that.

Vivaldi and Edge are closed source internet browsers and similar as far as privacy goes.
I’m sorry, this is just not true, just look at their privacy policies. They are not even in the same league.
That aside, the owner has said he plans to take it to court. Maybe we will finally know what happened.

I mean, they clearly care, they do run privacy guides and some other stuff and that one comment doesn’t really prove otherwise. But they are a weird bunch with what tools they allow and what posts. I lost respect for them when they allowed a post to stay up claiming vivaldi is “worse than edge” for privacy.
I think you’re spot on with account thing. When I first came to the fediverse, I thought the distributed system was cool, but then I saw the interoperability between different software and though ok, but why would I want to?
If someone posts a peertube video within the medium of lemmy, I also want to discuss it within the medium of lemmy, after all, there’s a reason they posted it here. I want to do it in this community, using this identity. If I wanted to comment on peertube, I would go to peertube.
So the only benefit I saw was that you could use one account for all my social media, as convenience. But of course, that’s not how it works. The interoperability is just a half baked sending messages thing. Because they are fundamentally different platforms not carefully designed to work perfectly with every other platform in the fediverse. There’s no central account, you sign up for a specific software, on someone’s instance.

I don’t think there’s any anti-mozilla, pro-chromium squads roaming the wilds, but yeah, Mozilla has not fallen, they’re just working on a spec, with engineers from facebook, to enhance privacy.
The reason why I said it’s a good thing: do you honestly trust the likes of facebook/google to design something privacy oriented, even if their intentions are entirely honest? No, of course not. Regardless of their intention, they have been built, as companies on principles opposing such design. They had to be. They don’t have the people, the experience, the methodology, the principles etc.
So it’s great to see them joined by someone who does (Mozilla) who I’m sure they’ll respect if they want to have the proposal accepted not just by W3C, but the greater community.

It’s an apt comparison, but do you want complete abolishment of all forms of telemetry, tracking or advertising? Or perhaps more relevant, is that Mozilla’s goal? I don’t think so. See this post by them.

Many people are upset about this, but it is in my opinion an excellent thing. Mozilla and Facebook are working together to improve one aspect of Facebook’s privacy
It’s not like Mozilla is shilling and getting paid off, as some people seem to think.
This is how privacy is really improved, by working with the companies and governments that have power in the space, not by sitting in your cave using only librewolf and tor, and refusing to use anything you don’t build from source and self host.
That only helps you at best, and the privacy abusers (google, facebook) will just ignore you.

There’s a key difference: nfts deal with ownership on the blockchain, whereas foss deals with ownership legally. Nfts are just a token and a url. Turning an anything into an nft just means you have certificate saying you own the original “authentic” copy, but in no way limits people from viewing, modifying or distributing the source.

From the article:
Basically this Rust-written, MPL-2.0 licensed software aims to automatically configure the kernel’s CFS scheduler and dynamically deal with process priorities
That is, it’s not an entirely different thing. It wouldn’t make much sense for system 76 to directly add it to the kernel, so I guess it’s a sort of extension…
Most americans kids don’t know and what they do know they don’t hold that negative an opinion of as you do. America is still better than most of the world for a child.
