Success, is when your work produces a bunch of value for you and your employees, financially uplifting an entire group of people.
I'm sorry but I personally can't see how selling your business so that a bunch of people who are already rich can use it to make even more, is a good thing in the long run.
It's one of the practices that is keeping the already rich on top, and more often than not leads to the business adopting the same opressive profit focus as everyone else.
No-one looking to buy up or invest in companies is doing so for the good of the product or employees. They might claim they are, but ultimately, the whole point of investing, is getting a return. And once that priority is introduced, the people and the content will never again be first.
