A corporation is a bunch of people cooperating to achieve a common goal.
There is a very important factor that heavily influences (perhaps even controls?) how people act to achieve that goal, and sometimes even twists or adds goals.
Is that corporation publicly quoted in the stock market or is it private?
Look at how steam behaves, it's private and more ideological VS how many other publicly quoted companies, whose CEO often sacrifices his own corporation's long term survival for the benefit of short-term profiteering and some hedge fund manager's bonus.
Both need profit to survive, but the publicly quoted company is much more extreme.
When people say corporations only look to profit, what they really mean is that publicly quoted corporations will do everything possible to maximise short term profit at any cost. Is there a CEO caring for long term? Either he will be convinced to change or kicked out. It's almost impossible for someone to resist these influences in publicly quoted companies. It's just how Wall Street works and if that doesn't change neither will corporations.
The people running the world of finance and their culture are what causes enshittification and pushing a zero-sum game to extremes.
That short-term individual success is at the expense of the wider long-term success.
If 10 people live in a lake and I fish more than everyone I will be better off that others. But then everyone else will seek the same individual short-term success because my first step in being an asshole was not punished. We will all end up starving in this scenario. A central authority agreed by all to manage this situation fairly is the way out. Rules agreed to in common beforehand and enforced by a neutral party.
