By the end of the day, we'd signed up for streaming via Amazon Prime (which includes Dora). And cancelled it via Netflix.
Really bad user experience and communication, combined with a very passionate target viewer for those shows who doesn't understand license negotiations.

Well, if enough people do this, it will certainly give Viacom greater leverage in negotiating with Netflix.
But we were upset about the lack of warning, and upset that the two sides had given up on negotiations in the first place. I can roll my eyes at the situation and grumble and move on with my life, but I'm an adult. Toddlers and preschoolers are not quite so savvy.
We may make some effort to get our daughter less attached to Viacom programming as a result, too. (If for no other reason than self-preservation for when they try the same thing with Amazon!) But that's a longer-term project.
