Sorry, are you trying to prove beyond a doubt that you are dishonest and statistics-illiterate?

which is why I said:

It is entirely rational to assume that an English-speaking person on the Internet is from the US, given no other information.

No, you wrote:

**The US has more allocated IPv4 addresses and more users per allocated IPv4 address than any other country, by wide margins **- and IPv6 adoption is not that widespread yet. It is entirely rational to assume that an English-speaking person on the Internet is from the US, given no other information.

So your assumption is based on a gross misinterpretation of the statistics you presented. Your incorrect interpretation of the graphs would put US participation at about 99,99%, which is obviously ridiculous.

Also according to Wikipedia the percentage of English speakers located in the US is lower that 20%. Does this mean that only 1 in 5 users is from the US?

The point of using the IP address statistics is to show that the vast majority of websites on the Internet were created in the US for the US market, and that is still true today.

That's not at all what these graphs show though.

Also, while I agree that most websites might be US targeted towards the US calling that 'vast' is bit of a stretch.

... and realistically not many people outside the US had any interest in the internet in 1983.

I gather you've not been around then. Almost none had any interest in "the internet" until the mid 90s - this includes the US. Partly because what you refer to as "the internet" was called WWW back then and started only 1989. People had been very anal about this until about 2005 - I guess you haven't been around then either.
