>Would you believe me if I told you I would rather have the chink government spying on me than my own (U.S.) government?
Yes, which is why I personally use Yandex unironically. I trust the Russian more than I do Google and the rest of Silicon Valley. Still, the Chinese are not as less trustworthy as you might think. Looking at the various videos articles from /cvg/, you watch as many Chinese both official communists and unofficial shitheads deliberately botch up products before they are shipped. The Chinese are also known to root many domestically made devices with backdoor software and hardware. Sure, they might not be an existential threat like the U.S. Government, but the companies that make tracking devices are selling and using that data without your permission, often maliciously. To completely ensure a secure phone with secure components in America, while expensive, obscure, hard, and tedious, is at least still possible. We ought to enjoy and use that freedom while it lasts.
>Do the librem 5 cellular data/bluetooth/wifi hard switches actually work as a way to avoid any triangulation methods?
The purpose of a phone like Pine or LibreM is lessen the footprint of a communication device you cannot not use so that whatever data a mobile company, NSA, and the like are getting on you, it won't be much and won't cause severe future legal or social problems, if any.
Like the other anon said, the cell phone by it's very nature tracks your location. It cannot work without doing so. If you truly wanted to be safe from any and all phone tracking the only way to win is to not play that game. Welcome to the brave new world!
