I'm prone to believing that a lot of those things presented as "leaks" are actually the company in question doing it by themselves behind the curtains - because let's face it - people want sensationalism and they won't shut up about something like that.
Someone forgot an unreleased phone at a bar? I call bullshit.
Directional cables kind of make sense in an analogue, single-ended connection if it’s about the shielding being connected to ground only on one side… although I haven’t tried it in practice. Still, it has nothing to do with signal directionality, just noise rejection. The ground lift switch on some devices does the same.
