My observations largely match your own, and also applies more generally to non-technical interactions online. I help manage a group that runs a local LAN, and have run into both the general language issues, and people making long, incomprehensible requests that have major LLM smells.

I don't think it's just availability bias however, I think it's mostly a case of divergent linguistic evolution. In terms of the amount of people who speak English at an A level, India has the largest English speaking population in the world. With that, and a host of other native languages, came a rapid divergence from British English as various speech patterns, idioms, etc, are subsumed, merged, selectively rejected, and so on.

The main reason you don't see divergence to the same extent in other former colonies, even older colonies like Canada and the US, is that the vast majority of the colonists spoke English as a primary language.
