But that’d already entail control over the whole Signal AWS in- and egress as well as any VPN you may be using and/or your local ISP. And then you still have to prove the actual link to the natural person. At that point we’re speaking of a threat level assuming the US DoD as adversary. While not impossible, I think if you’re willing to pick that kind of fight, you’re clever enough not to rely on Signal (or most digital communication).
Signal is not WhatsApp, there aren’t a lot of data points linking your communications to end points in the same way Meta does link them.

In all seriousness though, Peterson lost the plot long ago. His concept of Post-modern Neomarxism is complete bullshit and at worst reminiscent of" jüdischen Kulturbolschewismus". His schtick is mostly stating obviously true things, like “clean you room”, but then uses these axioms to hint at a larger, more all-encompassing truth that uses far-right rhetoric. But if he’s put on the spot, he’ll just fall back on his obviously true position and ask what’s wrong about them.
