Clevo. They are a whitebox laptop manufacturer so you will find they are OEM for several smaller brands like MSI, Sager, and others. Yes they are Chinese market, but every laptop is made in China these days, even the big American names, so that part is unavoidable. If that truly is an issue you can't get around, you'll be happy to know that System76 is moving towards producing its devices in house in the United States[1], though I have no idea if the recent tariff wars have affected that situation.

But I think the real culprit is that all of the organizations the grandparent poster listed distribute proprietary software which is untrustworthy to begin with. Proprietary malware isn't hard to find (see https://www.gnu.org/proprietary/ for an organized set of links) whether it came with the OS pre-installed on the computer or installed later. So long as it adversely affects the user and leaves the user with no permission to inspect, alter, and share the software (only permission to run the malware) the situation is bad.
How about we stick to the facts we know, which is that all manufacturers but Apple have done these incredibly user hostile things.
With the amount of attention on them, if they did it, it’s bound to come out sooner or later.
Until then, though..
Zbooks seem to continue the tradition. Dell's Precisions are great, too.
Haven't had experience with the newer Thinkpads, the design, materials and being owned by a Chinese megacorp kind of drove me away.
