If Cloudflare offer a product, for a particular purpose, that breaks existing conventions of that purpose, then it’s Cloudflare.

Well it doesn’t break the conventions of the purpose they offer it for. Cloudflare attempts to block non-human users, and this is supposed to be used for human-readable websites. If someone puts cloudflare in front of a RSS feed, that’s user error. It’s like someone putting a captcha in front of an API and then complaining that the Captcha provider is breaking conventions.

Not really. You wouldn’t complain to a fence company for blocking a path if there were hired to do exactly that

Yes, I would. Experts are expected to relay back to their client with their thoughts on a matter, not just blindly do as they're told. Your builder is meant to do their due diligence, which includes making recommendations.

They are enablers. They get part of the blame.

I contend this wasn’t an issue prior to Cloudflare making that an option. Sure, some IDS would block some users and geo blocks have been around forever. But, Cloudflare is so prolific and makes it so easy to block things inadvertently, that I don’t think they get a pass and blame the downstream user.

It’s particularly frustrating that they give their own WARP service a pass. I’ve run into many sites that will block VPN traffic, including iCloud Privacy Relay, but WARP traffic goes through just fine.
