Everybody loves to hate BendingSpoon, but there is a lesson here. They consistently rewrite the code of their acquisitions with a tiny team, fire everybody and are able to maintain and improve the product. They basically skip everything but engineers, and they are kept at a minimum. Feedback from users is the products they take over 1) become more expensive, 2) they ship features waaaay faster.
It looks like next generation private equity, and my guess is more houses will start copying them.
These stats don't account for the much more common case of people that start renting a house and stop paying the rent indefinitely because technically it doesn't fit the definition of "okupas." I've seen estimates of that number being as high as 1% of the people renting, making it ~30K extra people living on a house they don't own and are not paying for.
