Dare I say it but when a company has a certain level of dominance in a "channel" then they need be subject to regulation.

A channel might be any means of reaching customers whether a telecomms provider, a form of media, or in this case, a device app store.

The total control a gate-keeper has on the survival of tangentially related companies by eliminating their access to customers is simply not right. They should be held accountable for their incompetence or ill-will.
