Major Internet companies are still American-centrist, after all, many of them are American platforms and concerns (if not only concerns) American interests.

Google for example, they provide CAPTCHA to train their own AIs. Since Google mainly operate in the US, it make sense for them to optimize for Americans.

Another example is Cloudflare's CAPTCHA page, which is created based on measurements of American/first-world networks. But if your connection is "sub-optimal" (a.k.a, not first-world enough), it is possible that you don't even get the chance to load the verification scripts before the server cuts the connection and force a page reload, forming an infinite dead loop.

I feel the Internet is no longer international anymore, especially after all the AI scrapers. Now days are the days of contraction and everyone is guarding their own boring little caves against what they've defined as "thievery/stealing", while putting very little effort into actual useful thing such as gaining market and user (a.k.a expansion). The CAPTCHA implements maybe a sickness of it.
