Yeah I agree with the article, people will just say "Do not use in California" then....F off. OSes are VERY different all over the place. I dont see this as enforceable. Linux in itself is multi-user. Everyone is just going to put some bogus year for age and continue on. I also dont see websites caving and adding it all in because that would cost a metric ton and be inconvenient for everyone involved. What about server OSes? OSes that have a machine as the only user. Or embedded devices? It also does NOT protect Children in any way.
