Don't know why this is downvoted. If it's acceptable to point out that a link is paywalled or hugged to death, it should also be acceptable to point out that it's unsolvable-captcha-walled or only lets certain browser fingerprints through.

I think there's a sympathetic prevailing sentiment as it relates to paywalls. I don't know that Cloudfare is regarded as unnecessary or negatively (though I'm certainly open to that argument!).

People who use Cloudflare typically don't even have concrete reasons why they are using Cloudflare. Some do, but the typical one doesn't.
