Minimal. I'm behind Cloudflare and 90% of the traffic is still scrapers. I don't think they're serious about the long tail.

I think the main thing Cloudflare is trying to do is block direct traffic from frontier labs and then start charging them for access. They might end up shooting themselves in the foot, as this simply empowers sketchy residential-proxy outfits to undercut Cloudflare and sell the data to labs for less.
