This alone will be enough of a deal breaker for privacy nuts, such as myself. If I'm going to use your service, you just champion privacy. This means no marketing gimmicks.

Sorry. For me this comes no way close to being an iMessage alternative. Even if you become a privacy champion, you still need to expect us to trust your servers, which is a tricky thing without end to end encryption.

Maybe an alternate model is to get funding from big corporate sponsorship and have a distributed network that could be hosted on our own droplets (using open source, of course). You can then have a paid hosted saas for those not technically ready to self host. Until there's a solution out there that does just that, I'm very unlikely to bite.
