> Signal is probably at the current time the last non-corporate messenger that is secure and is easy enough to setup and use (other suggestions like Matrix have a barrier to entry that is too high because it requires both technical knowledge and the ability to find your correspondents). It can't be acquired due to it being a non-profit foundation so it's likely to be around for a long time to come. Threema exists does e2ee, does not require a phone number (but in practice it is much easier to use it), is fairly easy to setup and has been around for 9 years now. The only downside compared to Signal is that backups are slightly more cumbersome because the password is required to be 9 characters instead of four digits as in Signal. But I don't trust Intel SGX so that is a win in my book. Since Signal currently seems to live off of the loan from Brian Acton, I wouldn't assume the future to be quite as rosy as you paint it to be. Group video calls and everything Intel SGX must be quite expensive.
