For anyone else that was confused, apparently there is an alternate usage of the word 'Cleave' that means 'to adhere' (rather than 'to cut' or 'to separate').[0]
I almost feel like that specific usage should come with the 'archaic' tag, but it's reasonably common in slightly older novels, I think? Things like "He still cleaves to the imagined ideals of his forefathers".
It definitely tends to be used in a more philosophical sense than the very physical "cleave a block of wood in two", though.
I know... "sanction" is one of those words that means it's opposite too... a "contranym"
But it's the word they use in international federations.
You are right... the first ever electronic game of any sort to be officially recognized as a sport. Extremely cool.
Thanks for commenting.
I also misread the headline as the latter instead of the former, likely because of the latter type of sanctions being in the news as of late.
