One possible answer to both of your questions is "with legislation", and I feel like to some extent a tightening of the rules here is what Solid anticipates. Perhaps not to the point that we could expect the big players of today to adopt a platform like Solid, but perhaps where the companies of tomorrow looking to avoid the headaches of compliance see offloading data storage to a dedicated entity managed by the user as an appealing option.

I think that may be the answer! If data is toxic waste then offloading the storage of toxic waste may be the new way to focus on your "core competency" of running your service.
