This seems unlikely - if you're tech savvy enough to replace a TV with a laptop, you'd expect those people to be able to find a free stream.
Living in Britain obviously there is zero MLB tv coverage, and MLB.com has an added tax of 20% on top of the normal subscription fee, which is also not available in £ so you also get screwed on the exchange rate. Therefore, every Jays game I watch live (which because of the time zone difference is normally just the early games) is a free stream, and I've never had an issue finding one, most of the time in HD.
Is there any baseball equivalent of a highlights and debate show like Inside the NBA (which is freely available on YouTube) that airs in either Canada or the USA? That kind of show can help spread popularity of a sport, as part of a wider marketing campaign.
