So you’re suggesting a blanket right to redistribution to all property? It feels pretty generally accepted (and non contentious) that the creator of a product has a monopoly on its distribution and can chose to distribute in as many or as few places as they like. Otherwise I’d be well within my rights to ask you to give me the contents of your hard drive at my convenience as you would not be permitted to control the distribution.

It turns out that with the current rules around monopoly rights of creators, many rights holders actually prefer to widely distribute, so I wouldn’t say that this makes it “even more concentrated” as the majority of content would be.

Some content will probably only be available in a first party store, but just the fact that there are competing stores is good for the consumer.
