Ubuntu's modified GNOME desktop feels less polished than base GNOME, and the font rendering is part of GNOME, not something Ubuntu does special. There's little reason to use it over Fedora.
Matrix does not have the features of Discord. It's far closer to a Telegram alternative. It doesn't even have voice channels, a very basic requirement for a Discord alternative.
HIPAA does not apply to as many entities as it probably should. These services likely avoid it by considering themselves wellness services, rather than healthcare.
I see. I've never had an issue with it forgetting my spot in a show, and as far as I know my friends haven't either. Haven't had connectivity issues either.
Bluesky is such a huge improvement over twitter and so many people are just ignoring that. Yes, the app is centralized, but you can still host your own data if you choose. Plus, the customizable feeds, algorithms, and moderation lists are all great.
Community-based platforms aren't receiving as much attention because while Reddit is getting worse and worse, it has not reached the level of enshittification Twitter is at. Most people are still going to keep using it. Twitter on the other hand is reaching the point where huge amount of people are leaving, making alternative microblog platforms very relevant.
You only see the likes from your instance, they don't federate to others. This is a purposeful decision made my the Mastodon team, but I don't agree with their reasoning behind it.
It doesn't need to be, as long as there is also a proper default for those who don't care. Lemmy and Mastodon both unfortunately lacked this during the periods where they both had the most opportunity to grow.
Nowadays Mastodon does it pretty well. Users don't need to know anything, they just download Mastodon from the app store and register on the instance it chooses by default.
I just opened BlueSky to see how many people I followed using their own PDS instance and the fourth post in my feed was from someone using one, and the 7th was from Washington Post who also uses their own.
Bluesky does have federation, it's not at the level of Mastodon's, but it's improving. You can host a personal data server, which lets you host your account from your own server. You do still access this account through the main BlueSky website and apps, but authentication is done through your own server.
That is the owners account from the official forum, which is known to be real. The Lemmy account was a fake that copied their name from that account.
