And without wanting to insult your intelligence, none of the features you listed were something I really wanted or needed from SMS. Its just that, a short message service. Relying on encryption in a world where each and every country does an attack on E2EE every two years is unrealistic. Read notifications are just a "let me spy into your day" feature that I, no-control-freak, never ever needed. The rest also just reads like a corporate feature list, many nice to haves, but nothing, for me at least, essential.

I am fine with using SMS, and it has always served me well.
