No offense but that's not really relevant to the question at hand. The article debates whether the American tech sector is conducive to American national security, not whether your phone is sufficiently libertarian.
the points raised are perfectly valid. The tech sector is out of alignment with law enforcement, out of alignment with the American military sector, potentially more in alignment with foreign governments, and social media companies may be destabilizing society at a cultural level.
So in short the American tech sector is a competing power center that sidelines the interests of the state and the nation. Funnily enough China which is mentioned multiple times ,despite popular perception in the US, actually does have the same problem. Which is why they did exactly what the article demanded, which is pursue anti-trust measures and bring the hammer down on big tech.
