"Just don't use untrustworthy hardware and software" isn't really viable when Windows, MacOS, iOS, and Android (incl. Play Services) are all proprietary closed

"Just don't use untrustworthy hardware and software" isn't really viable when Windows, MacOS, iOS, and Android (incl. Play Services) are all proprietary closed source operating systems, covering over 90% of all consumer computing devices. Before you include all of the IoT space, which also tend to be proprietary. So creating a system where I, as a consumer, have no way to inspect the communication my devices undertake removes my rights and safety in deference to companies that really just want to make it harder to block ads. I take issue with this entire model. The fact that PKI has had piles of issues with bad actors who are supposedly supposed to be bastions of trust doesn't give any example this is a system we should trust, much less have browsers force people to utilize and scare people off avoiding.
