Blessed be those who didn't have to go through the trouble of learning English. Some might say that learning Japanese or Icelandic might be the most difficult task out there, but even the most complicated aspects of those languages have some kind of logic behind them. English, on the other hand, has some truly nonsensical characteristics to it and a plethora of arbitrary rules.
Those with English as their native language never have to consciously work through the kinks of spelling out Wednesday or why writers write, but fingers don't fing and grocers don't groce. Learning English as a secondary language is a real minefield once you figure out the basics and step into more specific areas. And these people decided to point some of the most confusing things out there to prove their point. English is a weird language and at times makes absolutely no sense, especially for a language that is so widespread.
To be fair, many linguists would easily find a logical answer to most of the problems presented in these messages, as English language has a lot of nuances (like words being borrowed from Latin and Greek, or the fact that some words had their origins lost or they ceased to be used in spoken language). However, that doesn't mean that they still don't fail to confuse people trying to learn the language, as even the most sound explanation might seem nonsensical when the original problem could be solved by, well... changing the language? Ah, let's leave this for the linguists to figure out and non-native speakers to be confused about, right?
