Google Voice doesn't need to be installed on a mobile device. I have my Google Voice accounts (yes, multiple) set to forward SMS to me via email.
"I personally no longer trust Signal. Moxie's departure stinks like a canary."
I never really trusted Moxie to begin with but events like this make me wonder all the more if Signal is really being run from Fort Meade. Fortunately for me I used Signal as my "non-secure" messaging platform and use other messenger options for secure comms.
Personally I really liked Wickr Messenger (no phone number required) but they were recently acquired by AWS :-(
edit: Also looking up Wickr now it seems like they ended up specializing in providing secure messaging FOR the government (and even are the only ones to pass some NSA specific test) so maybe that was not the best choice.....
Which events are you referring to here?
