Couple of notes:
- the UK, or rather UK trade unions, basically invented the concept of modern cooperatives 150 years ago.
- by now, cooperatives have effectively been out of fashion for decades. Even the flagship Cooperative Bank has recently been de-facto "normalized" into a regular business.
- the cooperative model can, however, still be attractive for small groups of artisans, like software developers. Hence the link from parent poster. This doesn't mean that it's been "adopted" at large scale, or seen a mainstream resurgence - it has not.
