As I understand it there's robust evidence in support of the hypothesis itself (GMVH), and this paper was an attempt to model how the effect could come about.
It looks to me more like it was retracted for being distasteful to the journal editor's wife.
Wouldn't that be a win? Don't people read & reference these published, reviewed, non-retracted 'wrong' papers with the assumption that they are right?
Alternatively, they might have retracted to have the bullying and intimidation stop.
It's like saying a kid hands over his lunch money everyday to the school bully because he realizes his mom actually wants the bully to have more spending power. Or the business owner truly wants to hire the mobster as clearly you never know when some random pyromaniac decides he feels a bit cold.
