There was also that attempt at destupifying English spelling

There have been plenty over the decades

The Voice Of America has a standardized Simplified English

That’s a good thing but not at all what the meme is about. It’s about words like color vs colour, center vs centre, … The American is arguably easier (and I say that as someone who learned British English at school) but it’s not simplified. Simplified would imply that British is older which isn’t the case. Pre-standard was “anything goes” on both sides of the pond and you can argue historically for what every you like.
