That's a cynical take, but a more positive interpretation is that pivots are needed if your company isn't actually solving a problem. Otherwise people would pay for it, and the founders would be getting rich. So you need to pivot until you actually create a solution to a problem that people will pay for.

One that you apparently agree with, given the rest of your comment.
> you need to pivot until you actually create a solution to a problem that people will pay for.
In other words: You don’t care about the problem, you care about the profit from selling a solution.
If a startup is “created to solve a problem” and then pivots to solve a different problem because the first one wasn’t profitable, that means profit was the priority, not solving the problem.
