So the article explains that official tournaments use a unique words list that contains a lot of generous words like "zzz" and "aa". Mostly intended to allow high scoring words for people who studied their list.
The company that maintains the list has added a lot more of these "not a real word but it scores high so we added it" words.
For some highlight words from the article: MIREPOIXS, HORSEFEATHERSES, SUBSPECIESES, GRATINEEED
Players are complaining that high level tournaments are basically going to be competitions for who knows the most gibberish from the tournament word list and it is alienating the general population from joining tournaments and scrabble clubs.
