That stupid Newsom age-gating OS bill is pure political theatre. It won't affect Linux -- too many capitalists would be inconvenienced, and inconveniencing capitalists is the last thing capitalist darling Newsom would do; he couldn't even be bothered to support a modest 5% tax on billionaires.
Linux is here to stay -- it runs the internet. And it will always be customizable, because that's part of what gives it so much value.
