The key difference between your car and YouTube is that YouTube (or Facebook or Twitter) makes part of new media that has reach far enough for commentary published on it to shape public discourse. This is especially big thing within young democracies for which new media is de facto mainstream media. Our markets are usually regulated to make sure monopolies don't arise, and if they do, they may be forced to downscale, split or open market for competition. This is not the case with major social media sites, that answer only to the mighty dollar.
