I agree with what you are saying, but I was talking specifically about digital distribution. Closed platforms like Kindle definitely cause some lockdown, but Kindles are relatively cheap and replaced as often as yearly. If Amazon did start gouging on prices, a lot of people would switch to Kobo or Nook. With digital distribution, you can guarantee that everything you're selling is always available for free (with the risk of legal fines) from other channels. Companies like Spotify, Netflix, and Amazon's digital distribution are aware that they are competing with free and tailor their services to be worth the cost. Physical goods that require factories and distribution centers will be a barrier to entry for a long time, at least until commodity 3d printers can compete with large-scale factories, which will take some time.
