I don’t know too much about lemmy yet, but all of these things (tagline,siudebar and legal info) sound like they should be controlled only by admins, that should be able to add html code anyway (since it their website).

What about pinephone?

I think people often forget federation is not a new thing, it’s a first design for internet communication services. Email, which is predating the Internet, is also federated network and most popular widely adopted of them all modes of Internet communication. It also had spam issues and there where many solutions for that case.

The one I liked the most was hashcash, since it requires not trust. It’s the first proof-of-work system and it was an inspiration to blockchains.

I disagree. There are many FOSS decentralized projects that are still running today, including XMPP, that are doing fine and make even better and more secure software than Signal. All centralized privacy apps so far closed or started sharing data with governments. Statistically that is far more likely scenario then a popular FOSS app to lack devs.

Why would you trust Signal more than XMPP that uses same encryption? I think people are just afraid of things they haven’t heard of, even if they have been there for longer and have a better reputation. This is why marketing is the biggest business in the world, google and facebooks only revenue is selling ad space and they are richest companies in the world. Fight that marketing, learn a bit about XMPP and you will see it is far better than Signal.

Exactly my point is that if it closes we will have to push for new apps anyway and it is better to do it now, before more users potentially use SIgnal and are left without their app.

Email is federated as well, but I never saw anything I could call email instance wars. You can use whichever you want, no one really cares.
