This list puts US at ~297m English speakers which is the largest group from one single country, that is true. But 297m / 1,537m = The US has 19.35% of English speakers globally.

You are likely also greatly underestimating current internet connectivity, older smartphones have changed things for poorer countries a lot over the past decade. For example, India has only 62.6% of people as internet users - but that’s still 880m people and probably most of their 125m English speakers. Nigeria has 63.8% internet users, but that’s 136m internet users. And they also have 125m English speakers, who again, are more likely to be the people who can afford an English education, and also a smartphone. And then there’s Pakistan with another 100m English speakers and 70.8% internet users, etc.

Just 3 countries, (2 of which were 1 country 80 years ago) and you’re close to that 300 million count already.

The list also gives US as 92.4% internet users, for what it’s worth. A little less than 97% and not even in the top 20 countries by percentage, which is surprising.

The internet is less American than ever. It’s just that most non-American people probably have non-English language spaces they can choose to gather in addition to the English-dominated spaces. Americans, on the other hand, are more likely to be monolingual English speakers and so they concentrate in the English-dominated spaces.

And non-Americans are all so used to people assuming American defaultism in English-dominated internet spaces because it was historically hugely expensive to get online and was overwhelmingly American English-speaking, that it’s not even worth correcting when it happens the millionth time.

I’ve also put non-metric and US currency conversions in posts online many times. Not because I’m American or use them in daily life. It was just less annoying to convert them when writing rather than hear the inevitable multiple complaints about not understanding things in meters and dessicated jokes like “that’s probably $2 in real money”.

You’re either overestimating the accuracy of your assumptions about your online interactions and/or seeing selection bias from your immersion in otherwise culturally isolated spaces.

How convenient that a counterexample can’t be named

I feel like Luthor was a better counterexample for this before the model for his billionaire redesign was elected President of the USA.

Even so, Luthor hasn’t had quite the same volume of appearances as Iron Man, Batman, Captain America and the other rich superhero tropes.

People have grown up reading comic books and watching movies about generous billionaire superhero saviors. They want to believe that exists because it’s what they’ve been taught justice looks like.

Some provide screen-reader instructions, but most places barely remember blind people exist. It’s another example of people with disabilities being ignored and marginalised.

And then even if they do remember blind people exist, they probably forget there are people who aren’t blind who can’t do their tests for other reasons, like dyslexia or dexterity impairments.

And then you have hCaptcha who makes disabled people to sign up to their database to use their cookie.
