But the OP article is about a Stingray operation covering 30 blocks, and other discussion in this thread is about protests such as the anti-ICE protest which gathered cellphone info from the protestors. In those kinds of environments, if you don’t want to show up on surveillance, you’re much better off not carrying a phone.
Being more specific, this comment of yours is not supported by evidence:
> No phone actually stands out a lot in real life surveillance systems and will very quickly get you a bunch of additional attention because it’s so unusual.
But, if you’re getting your information from videos like the one you linked, I can see why you have these beliefs.
