I'm about to start paying for YouTube for the first time ever. Of course, they make it complicated because I don't actually want their bundled music service. And the "lite" version says most videos are ad-free. But what's preventing them from changing that deal the day after I sign up? And of course, once I become a customer, now I'm hooked, and I'm subject to their arbitrary price increases.

Of course, as a "free" customer I'm already subject to their whims whenever they decide to add another advertising layer.
