Tox has interested me more since it's inception, mainly because it's open source and completely relies on peer to peer connections. I've seen some other open source alternatives that aren't as light weight and still centralized to some degree. Wire, if it really wants to be a "Skype killer" in my opinion, should go open source and be more reassuring about how they are protecting our privacy.

I wish this one would market itself as a really good chat application first and privacy second. Privacy etc is of course important but it all feels far too tinfoil hat for myself and too technical I'd imagine for anyone else I know to bother with
