If you remember Windows Phone 8, it has already been tried and nobody (ahem, no company) wanted that.
No company is stupid enough to give up their content and infra and get none of the screen real estate.
I can see a parallel with hotels and OTAs, but in that case appearing on an OTA brings in sales. Showing $userA's content on $userB's screen won't earn any money from $company.
