Did Signal remove the phone number requirement only for new accounts? I signed up for it a long time ago so it’s probably too late for me unless I start a new one. I do like SimpleX, even though it’s hard to find people outside of Nostr who have heard of it.
Use nostr:npub1exv22uulqnmlluszc4yk92jhs2e5ajcs6mu3t00a6avzjcalj9csm7d828 messenger! It gives you the best #privacy protection.
Unlike #Signal it doesn’t need your phone number.
#Telegram and #WhatsApp not only want your phone number they collect loads of data and metadata from your device. Especially vile is the collection of your device‘s IMEI (device ID) and sharing all that data with companies to make money and with authorities due to the need to comply.
In authoritarian countries this metadata can cost you your life!

Doesn't seem so. First thing it asks is phone number. I assume they only added the option to share usernames instead of phone numbers. 
That’s too bad. Having a phone number should not be a requirement to sign up for anything anymore.
True. To get a signal account you have to provide a phone number. You never have to share that number with contacts and signal seems to be pretty loose with accepting VOIP numbers. Regardless you shouldn't have to jump through hoops for privacy.
#Signal is best for friends and family. #SimpleX for sensitive coms. You just have to work around the having to have contact with the person first in order to give them your QR
