I don't see it
To me, the barrier to the blob is the proliferation of single purpose, data slurping, possibly paywalled, apps.
The Washington Post app has a negative incentive to play nice with the New York Times app and vice versa.
No game publisher wants to play nice with other publishers and even within a single publisher there are developer rivalries.
Beyond that, in IoT, Ring doesn't want to allow mix and match with Nest and vice versa. The list goes on.
Basically the companies that write for the internet like the status quo.
