I've responded about your dated and obsolete experience with Ring on the other thread

now, is matrix even end-to-end encrypted? I don't think so, so I didn't mention it in a conversation that was primarily focused on keeping information away from unintended eyes. if it does, maybe it belongs, but I find that Matrix shares far too much information with its servers, and more so with its central server, so I'm not at all comfortable recommending it to people who are trying to minimize their online tracks.
