I was hoping the /s wasn't necessary, but just to be clear: my comment was entirely sarcastic. Signal has had its issues in terms of open source-ness (like that time they stopped publishing their code for quite some time) but the client and server are open source, and while they're not huge fans of alternative clients, they have designed their protocol so that it's practically impossible for them to refuse alternative clients, purely out of privacy considerations.

Now that Signal has usernames you can share, rather than phone numbers, I think the phone number decision is a lot less problematic.

Strangely enough, I did receive spam this week. Or at least I think I did, an account I didn't recognise with a profile picture of a woman I didn't recognise sent me "hi". This coincided with my first SMS spam of the year and spam on an email address I used for one specific company, so I guess they've been hacked and had their database dumped. Maybe I'm just lucky, but spam just isn't a problem for me.
