To make it clear to those who are misunderstanding: that’s a list of companies that host matrix for you. They do it at a good price.
If you and your friends chip, it’ll be a few bucks a pop per month to have your own private server with voice chat rooms and video chat rooms.
It’s all opensource and contributes to the ecosystem. Best of all, no age verification because the data is yours.
This is also why bluesky picked up over all the other twitter alternatives. The average user doesn’t want to learn all this shit, they just want to use something that works (which in that situation is unfortunate, because Mastodon is right there and works perfectly fine out of the box with their default public instance, but it is what it is I guess).
Realistically I don’t see Matrix picking up as a widespread discord clone. Just the entire idea of Matrix needing a protocol and having different clients to choose from is enough to turn a lot of folks away from it. Meanwhile, Stoat is practically building a 1:1 discord clone, and is much easier for the average user to understand.
