This argument made sense a month ago. Unfortunately he really hasn't shown any improvement since then that would lead me to agree with you on that point.
It's now a situation where he has to either find enough new people who agree with whatever his approach is or /win people back/ - both of those are quite a bit harder than keeping people who already loved the app.
I also hope he - or someone - is able to recover Twitter. But I'm not betting on it at this point.
