Eh. We should want innovation - to "let a thousand flowers bloom". But when companies start getting so big they are a detriment to society in some way, we should regulate them.

We let train and oil companies do their thing in the late 1800s - which helped society. And when they got too big and damaging in the early 1900s, we regulated them. We're on the same course again, I think.

The same way I 'volunteered' for Selective Service in the US when I was 18.

No, way different.

You can choose to not use the internet, but that's probably akin to choosing to living in another country to avoid registering for the secret service.
