Not only that. I also question how they pick new features to implement. For example usernames - I am not going to trust another "private" IM app username feature same as what Telegram and WhatsApp questionably chose. Compromise on this? Well, then even WhatsApp and Telegram are good enough with compromises.

Separate usernames completely from phone numbers. Period.

There's a reason Signal is still "US based". No, I am not talking about some CIA/NSA/DoD/tom/jerry funding conspiracy, just good old human obstinacy and hubris. They don't give a f about who uses it, it's about who makes and maintains it all.
