Sorry: I meant "why is there no LEGAL live stream of the World Series game"

I'm legitimately interested in the business rationale. There must be one, but it is non obvious.

My best guess is that by focusing max audience onto one platform, they can charge the broadcast advertisers more. Maybe it's hard to sell that $50M ad deal to Ford while also saying "well some of the people will see a Samsung ad because they're streaming it, but you'll get most people."
