I agree this is bullshit. But at least you can lie to the OS about your age. Technically it's almost the same as OS asking you "Pick a date and a number from 1 to 100 and I'll report it to the software / websites. But don't worry, I'll not verify you.". If you pick randomly (over age 18 or whatever), technically, you don't provide any useful information.

This would be the least of evils (such as ID verification). But a bigger problem is that the implementation is very flawed. It doesn't appear to be very effective. People, including children, can lie. Multiple people can share the same account. Also there are many devices that cannot be updated (such as embedded). My concern is that these idiots might introduce even more extreme laws when they see that it isn't efficient enough.

I hope it will cause so many problems (implementation, backslash, etc) that it will be eventually cancelled.
