@Petros The question might be best put to the author of the article.

@risabee

That was a rhetorical question. The whole article is quite a mish-mash of categories, as it was partially pointed out in some comments below it.
It is probably a good opening for someone to start learning about the topic, but not a 101 on cooperatives, even workers' ones.

@Petros That's fine. I was merely noting its presence. Even somewhat incoherent noise touting cooperatives is significant in an atmosphere in which such seems suppressed by the powers. Responses that come across as shooting the messenger may also easily be taken as suppression, hence "Tooted links ≠ endorsements" on my profile. 😎
