I wasn't actually trying to be contrarian, but okay.

I'm pretty sure I didn't explain how it's actually shareholders, because the board of directors isn't "the shareholders", but leadership of the company.

Valve isn't publicly traded, but it's still a corporation with shareholders, a board of directors, and the usual trappings of corporate leadership. They tend to operate in a not shitty way because their leadership isn't interested in sacrificing greater long term profit for lesser short term profits.
A private, family owned partnership style business can operate with a focus on short term profits over long term profits.

The safest way to ensure that the leadership of both of those businesses out as much money in their pockets as possible is to continuously maximize short term profits. "The shareholders" aren't the cause for that mindset.
