And they don’t even bother to implement it properly—for example if your site tries to follow best practices and uses a separate domain for your static assets, you will just get errors on your static assets, resulting in a page with broken styling and no images. That despite pissing off your users by having them go through the Google hosted captcha (which also breaks all the time btw[2][3]).
One of the websites that was horribly broken by this was Stack Overflow. As anyone trying to stay safe on public WiFi by using VPN can attest.
Coincidentally, Cloudflare has lost Stack Overflow as their customer recently: https://meta.stackoverflow.com/questions/323537/cloudflare-i...
They’re now behind fastly.
