Ok, I'm sorry for the hyperbole of saying "half the internet" if it's in fact 10%. But come on, that's still massive.

It's not a stretch for small businesses to be reliant on residential connections either.

No need to be sorry, it is a matter of how you define the percentage. If you would define it as "fraction of traffic generated by residential/home endpoints" you probably wouldn't be off that far. Maybe because Netflix does not use cloudflare, but if you say "CDNs make more than 50% of traffic to residential" you would definitely be right
