There's no clean separation between those things. The weakness and inadequacy of HTTP(S) and other protocols actively funnels people into the centralised services of big providers. It creates a world where storage is brittle and content is ephemeral, both directly due to its own failings and because it pushes people towards big providers who increasingly like things that way; and so on. Now human nature would be enough to tend to draw a lot of people towards lowest-common-denominator options, but a system which makes the alternatives frictionful and downright painful doesn't help either.
