Could this be a strategy to scare away overoptimistic stock buyers?

When you have a money printing machine that you don't expect to run forever (but aren't afraid of the future beyond, optimistic that you can still make money, just not that easy), as a publicly traded company you have the problem that eventually all owners who have similar expectations will have sold to more optimistic owners who expect nothing less than the money printing machine running forever. And getting even bigger while at it. When that ownership change has happened, the company does not really have any other option than to die trying. Deliberately diluting the value of the company with ownership in "definitely not a money printing machine!" before that happens could be a way to avoid that death march, a survival strategy.
