it probably could, to me that along with traffic analysis are things that fall more into state sponsored level attack. guess avoiding those chipsets is the way or disabling it, but only 3 people are going to do that. like i'd think that at least with intel it's basically a backdoor, probably would take a fair amount of effort for someone outside of them to exploit it. but i guess that doesn't stop intel from gathering intel, lol

there's a surprising amount of low-lying fruit that can be way easier to do for non state actors. Best to assume your ip address is known to be running i2p as public knowledge, and like just poking around the netdb will give info that can sometimes lead to deanon if not careful
