There have been community-run services going since Pebble shut down. My pebble behaves as though nothing changed to this day, except the lack of new features being released.
Yeah, I saw that there is something called rebble, which is great. I'm just wondering whether the company did anything to support this before selling. I'm not an open source absolutist, but I really hate the trend towards obsoleting hardware because a company pulls support. Community stepping in is great, but it's not always possible without company support.
