And the funny thing is that the WebGL context attribute they're asking for is not even the root cause, so implementing it didn't do squat. But it shows the attitude of Cloudflare to the open web: we don't care about mature and stable web standards, or the fact that you don't allow automating your browser by intentionally not implementing WebDriver or Selenium, implement these draft features unrelated to actual bot detection or we will consider your browser a robot and block it.
Cloudflare stays true to its image of being the scourge of an open web.
