They don't pay that well relative to the local market, insist you be in SF at the same time and only want full time. They can solve the problem by allowing remotes, having a few part timers or paying the SF standard salary. If you try to do a simple github pull request on the repo, it takes a very long time to do a code & design review so it makes possible maintainers discouraged from contributing.

It's the old choice triangle: fast, cheap, good: pick two.

Ugh. I don't want to be a downer but it sure seems that the pace of Signal updates is quite slow.

Maybe Apple or another tech company will step up and donate some resources to this effort.

Heck, I'd be for Apple to help with the UX of Signal leaving the OpenWhisper team to focus on the security tech...
