I wonder if there's even a reasonable way to delineate what should be regulated vs what should not. For traditional utilities, the line is pretty clear about who is providing me electricity. "Social media" and "cloud provider", however, are extremely vague terms. There are a few standout examples of what might count (FB, Twitter, ISPs), but there are innumerable examples of services that are clearly "social media" or a "cloud provider" but that clearly should not be subject to the burden of regulation. Maybe the distinction is as simple as userbase size, but that too seems like a too-crude distinction.
