The article isn’t specifically about the USA (the word “American” appeared once in “American English” when explaining the name Pi-hole). The CharlesW comment doesn’t mention the USA. The nik282000 comment says NextDNS is a U.S. company so U.S. government will have access to the data, it never said it’s only a concern for American users. I don’t know where you got the idea that this thread is specially about the USA. In fact, I assume the nik282000 comment is mostly for non-American users.
