This is a really strong example of how both the left and the right have been moving away from liberalism (ie, "classical liberalism," the general belief that people should be free to make their own choices and pursue their own interests) for the past 16 years or so. A bill like this could have just as easily come from Texas.

Practically, I think this is tough. How does a business verify their 20k Linux servers in AWS? What prevents Linux users from simply modifying their code such that they no longer do age verification? I think it's easy to imagine circumventing this one law, but this is another brick in the wall. Maybe your bank stops working on Linux. Maybe major websites stop working unless they get your citizen ID and age verification data from your OS. Maybe no one makes a browser that doesn't try to grab that information.

Not joking; stock up on books and keep a collection of media that you own personally. Perhaps your linux computer will start looking a lot like your PC from the early 90s: not connected to the internet, just used for word processing, some installed games, and media.
