You seem very frustrated personally for the lack of SMS support on Signal.

I don't agree with your take or arguments, and you seem to keep branching off pejorative comments on their organization and product instead of actually discussing the points. I think the conversation would be more productive if we focus on the same point, i.e.:

  * Focusing on what matters most is a good idea, as nobody serious about secure messaging uses SMS

    * Your argument: irony-covered "dropping features is not a good product development approach". 

      * My counter-argument: it **is** a valid approach, why support a feature that was useful in the past, but it is now dying/not aligned with your core value proposition?

    * Your other argument: their focus is on social networking, and some disdainful comment that "the competition already did it". 

      * My argument: how is catching up with well-established user behaviors across other messaging platforms a bad thing?

I remember when I didn't have a smart phone (I don't come from a privileged background, and this was 2009) and I used twitter over SMS. I really wouldn't care if they dropped support for it now, but back then, I would have churned.
