Yeah sorry I underspecified because the rest is implied in the context of the case. You add a contact to a group, of course they get the messages that go to the group.

Heck, even IRC (basically) works like that.

The entire point of the fediverse is to federate. Not federating by default kills discoverability and the potential for discoverability among other things

Trump dismisses Signal security failure as

“Our failure”.

Signal worked perfectly here: if you add a contact, they get the messages.

What failed was the Trumpist, like at everything else.

Since you mention stuff like “the video isn’t important”, “other services” (plural), I’d consider not just one alternative but several. The big problem with big name social media is that they provide a all-in-one experience that is designed for profit, and as such looks and acts worse than any of its independent parts (not to mention, the sum is artificially made more addictive to users).

• For publishing campaign materials itself, all you need is a filehost or filebin - something like pastebin.com but that allows you to upload and organize any kind of files. Any of the offerings in the FOSS market will do, but if you are going to focus on posting quickie (rich¡) text documents that are easy to build and parse I’d suggest a Markdown-based document bin like Hedgedoc.
• If your campaign is gonna run like a chat, XMPP / Jabber. There’s servers like Prosody or ejabberd that are easy to set up.
• If your campaign is gonna run in web “play by post” mode, any modern web forum system will do, for example Discourse. Heck, even oldie-style web forums might do, like phpBB.
• Voice: Jabber has access to audio IIRC. I’ve also heard very good things about Mumble.

Oh, do cry me a river while you’re at it. Pretty much every community everywhere has a general or memes room, those are for the meme gifs (or wait, these are webp these days…).

So basically, people use Reddit to search on the internet now because it’s real people, not shitty SEO content.

Excuse me what? Since when since Jun 2024 does Reddit actually have real people?

This pretty much. At some point one has to accept that the people who want to be saved can be saved, and those who don’t, can’t. We shouldn’t (reasonably or not) waste ourselves for the latter in spite of the former.

If I’m talking with people about the topical thing which is why I joined a room in the first place, the last thing I want is a looping autoloops fruityloops annoyance. Plus, not autoplaying and autolooping them saves battery.

Excuse me, Jabber / XMPP is about as old as I am!

XMPP / Jabber is better.
