1. Has strong norms against castle seizure or abandonment of the king's duties in kingdom upkeep
2. Has a federation of non-king castle owners strong and unified enough to force the former point.
Example: Valve in the early 2000s before or as they were building Steam to challenge the video game publisher model. 20 years on and Valve is still printing money, while Sierra Online doesn't exist.
Unfortunately Sierra had to accept the offer.
Moreover, Gabe Newell always had a controlling stake in Valve ever since 1996, so that prevents any shenanigans. There are comparatively few shareholders (than a public company) and they were all long-term, since Valve will likely never go public, certainly no year soon, or even be privately acquired; while Newell controls it.
In this instance your complaint is about corporate governance rather than tech; (how far back did tech people stop being in control at Sierra?)
