Can we not call literally everything "anticompetitive"? archive.is isn't a competitor of Cloudflare. Cloudflare doesn't treat them differently from any other site, they're not doing anything "to keep them down", their DNS product just has a focus that isn't compatible with archive.is' hunger for data.

That you might connect to archive.is directly isn't of any concern. You might also not do that, and they've decided that leaking data about the user isn't what they want to do.

It's not anticompetitive. It's not evil.
