Simple: For a company who's main goal is to make their share prices go up (even one as comically bad at it as Squenix), goodwill is a resource to be traded for more money. In the case of XIV, all of the profit (and talent)is being either siphoned by the executives, or reinvested in other games that will inevitably faceplant due to a myriad of reasons. Yes, this will obviously kill the golden goose that is XIV in time, but that's not the shareholders's concern, since they'll long since have sold their shares and moved on, and the executives will long since have stepped down with multimillion dollar bonuses.

It's called Maximizing Shareholder Value, and it's an ideology that has been destroying capitalism since its inception in 1970 by Milton Friedman. But most companies only got on the bandwagon in the 2000's, and we're now seeing the effects everywhere. Square Enix is no different. It's quite possible that Yoshi P's promotion to the board of directors was to force him to be beholden to the shareholders so XIV could be milked accordingly.
