I think you misread my comment, which didn't suggest that there is universal support for Signal among everyone, just among security professionals (I adopted the term "security community" from the parent comment, but I agree with the implied criticism that the term "security community" is largely meaningless).

A good way to rebut my claim would be to cite the most high-profile security engineer or security professional or crypto engineer or crypto scientist you can think of who recommends some other system over Signal.

Unfortunately, and to a large extent why people listen to "open source advocates", the community of security professionals has a surprisingly bad record when it come to things like risk analysis, legal matters, understanding how law enforcement or intelligence agencies work and other ”soft skills”. I trust security professionals when it comes to crypto. Anything else I'm not convinced they aren’t as incompetent as everyone else in software and maybe even more so.

So, I totally agree with this but would like to know more, specifically, about why you believe it, to avoid talking past you. What are your specific concerns?
