I'm interested, but not interested enough to join Discord.

You could join their AOL chat rooms instead.

I would except they've also put the setup instructions inside their Discord server as well.

PCLink has entered the chat

Yeah, such things really should at least have a matrix bridge IMO.

Can't even open that link on iOS without being redirected to download Discord. Pass

Strictly speaking, it's because Discord goes out of their way to block mobile browsers.

I've noticed this trend more and more with apps, reddit starting doing it too recently.

There are times when walled gardens work, when they make sense. This is not that time.

Why can't you just publish the open source on Github or something?

That's planned. Would be blasphemy not to.
