I’m not sure I understand this, tbh. Does that mean the P2P network works on a chat group basis? Or does the user explicitly choose who to build a P2P network with? And then, there are lots of follow up questions already looking around the corner.

Their website seems to explain very little and the app itself is closed source. Although there are open source dependencies, it’s for instance unclear whether they are complete. So I guess it’ll all come down to trust into the software and the company. Btw. their privacy statement allows the usage of aggregate data for marketing purposes and the sharing of data with third parties, such as search engines. And latest at that point I’d rather self-host a matrix instance.

I dunno. P2P traffic always seems to overburden light users and it would indeed require the apps to always run in the background to relay the traffic. Although the idea seems compelling I wouldn’t install the software on a machine of mine.
