Your point is correct but irrelevant to this conversation.

The question here is NOT "if Signal didn't leak your phone number could you still get screwed?" Of course you could, no one is disputing that.

The question is "if you did everything else perfect, but use Signal could the phone number be used to screw you?" The answer is ALSO of course, but the reason why we're talking about it is that this point was made to the creator of Signal many many times over the years, and he dismissed it and his fanboys ridiculed it.
