"Convenience in digital distribution" is basically the glass pearls market of the 21th century. It costs absolutely nothing to produce - but corp has convinced their customers, that they need to buy it, because thats the progress they were always missing out on.
Shiny.
Now with cloud backup.
edit: As to the people who are uploading their home made stuff to Amazons cloud storage, without paying for cloud storage. (But I have Prime, does that count? No.) I'm sure you have no actionable rights to that stuff as soon as the datastream leaves your PC.
And they make sure they dont encrypt it, so they can harvest your personal stuff like photos, etc. as well - because the business model we are talking about here is not cloud storage, but training algorithms on big data sets - thats why they are willing to give away storage to you for free.
Otherwise they could be held liable for when they loose your data, which is much too costly to give away to your customers, you only sell "books" to, because ultimately you want them to end up paying for Amazon Prime and buy their groceries from you..
The same way you go to a museum and expect to be sold your toilet paper there. Corporatized culture, what else do you have to say..
