This turned Signal into the defacto default in our org.
Last time I had to reinstall my phone I ended up finding an implementation of their phone-to-phone transfer protocol to emulate a "new" device I'm transferring to just to get a dump of the data (I'd share, but don't want them to close this option, since clearly the lack of export option is very much intentional).
Then I deleted Signal and begrudgingly moved to WhatsApp (in addition to iMessage which I've already been using).
WhatsApp, which is infamous by association with Meta, backs up to Google Drive or wherever.
I hate writing on a phone - anything longer than a few words I use my computer for.
Their developers are also very responsive to PR's, I have a couple GCC build fixes in it.
I really soured on Signal early with when running BB10, they would not let us fork and use/distribute websocket builds to get around not having google play services on available on that platform: https://github.com/libresignal/libresignal/issues/37#issueco...
I'm still a little sour on it now because there's still no way to transfer the identity since they refuse itunes/icloud backup, refuse any way to export a key, and I have to look at hideous corporate memphis icons every time I set up Signal new again on iOS (at least Android doesn't have the last thing).
I mentioned before, but I use mautrix-signal to be able to have a unified (except for telegram) messenger on desktop with nheko or element via matrix. It works really well.
Yes it does.
Whoever knows how to download WhatsApp, knows how to download Signal.
