I won't be cancelling by subscription because I don't have one :) I have found I get way more value out of subscribing for 1-2 months to a service and then switching to another or going a few months without any.

At this point, netflix will keep raising prices. Because they can, and because they have to as a public company beholden to shareholders. I'm not sure there are other markets or other products/services they could expand into, i think they've already reached a point of saturation.
