What barrier to your business or industry do you anticipate to be going away?

If a barrier to your business no longer exists, how will it affect your business? Will it allow you to grow more quickly? Or, will it remove a protective advantage that your business was hiding behind? Or, will it continue to be business as usual?

I am observing a business that had exclusive access to some very profitable product lines. The provider decided to allow other business to have the same access. It is causing chaos for the first company. They are scrambling to reinvent their business on the fly – no easy thing to do.

Have you witnessed similar occurences? What were the long-term consequences?
