However so many sites are using CloudFlare and other DDoS prevention and CDN services. I'm sure the NSA has fiber taps (beam splitters) at the point where the data travels unencrypted on the internal datacenter network.

CloudFlare itself might not even be aware of the taps. Or maybe only a few select employees know about it.

I think the solution to these problems is to reduce dependence on the Internet. It's now possible to torrent an entire library worth of books and have it all on your personal computer at home. 20TB HDDs are readily available, and constantly getting cheaper.
