And in places where CGNAT is in use, so that many people are on the same IP address, and botnets are active on that address.

I live in India in such a situation, and most of the time it’s not too bad, but I still encounter Cloudflare CAPTCHAs pretty frequently. At times, it’s been almost half the web is blocking you. And occasionally, it actually is blocking you, not just a CAPTCHA. It’s also not rare, when being more aggressively blocked, for a site to break because it tries loading scripts from another domain, which is then CAPTCHAing so that scripts just won’t load.

Back when I lived in Australia, I practically never got Cloudflare blocks.

The mechanism may be understandable and even justifiable to a considerable extent, but the poor definitely end up suffering more from Cloudflare than the rich.
