Scary that so much of the basic internet infrastructure is being managed by US companies. Maybe now the rest of the world will change and become more independent. We should have learnt our lesson long ago though.

Considering that the internet was invented and built from scratch by the US military, US universities, and US companies, why are you surprised? And who do you suggest could or should manage much of the internet backbone, if not them?

The rest of the world exports its talent to the US because they don't pay enough. There's no reason why the EU couldn't have made an Akamai or Cloudflare clone decades ago save for the money.

What do you mean? The internet is virtually entirely decentralized. There is no one central BGP router.
