Yes, I'm quite done eating Google's free lunch.

Waking the device up for each incoming packet would probably drain the battery. But yeah, I had descent battery life on Android without GApps with mails and two chat apps (Signal and Element) so this can't be impossible to achieve. The modem has to stay up for incoming calls, listening a few additional TCP connections is probably fine. Maybe it's less power efficient than a centralized solution but still very usable. We could also imagine a solution where the used service is configurable.

If you don't enforce 100% open source, you are less incentivized to fix broken stuff and develop open source alternatives.

The "open source but not quite" niche is already fulfilled and it's LineageOS and its friends. That's already done. So nobody loses here.
