If you're the alpha, you probably have the resources to hire an army of developer advocates to maintain your dominance.

If you're the underdog, it's going to be an uphill battle to take over the pack.

Instead, you could leave and find a new pack.

Sometimes finding an underserved niche that the alpha doesn't serve [as well as you could] will allow you to grow until you have the resources to compete with the big dogs.
