> You are assuming he bought the building with company resources. If he spent his own money/took on the liability personally, that is his business.

It would be his business if he rented out his property to an organization that he can't sign contracts for. But as it stands, he is transferring money from an account he only partially owns (but fully controls, with legal obligations to his co-owners which he seems to be breaking) to an account that he owns fully. It's a sneaky way to give himself a raise that is easier to get past the board. The article even cites WeWork with "approved by the board or an independent committee", which implies that not all of those arrangements happened worth explicit board approval. How he got into the possession of the means by which the transfer from controlled-but-only-partially-owned to owned was facilitated is an unrelated topic.
