Remember Bandersnatch? Netflix Saved Your Choices

Black Mirror’s Bandersnatch is a choose-your-own-adventure game that went viral. As it turns out, Netflix saved the choices you made.
He found that Netflix is tracking the decisions its users make (which makes sense considering how the film works), and that it is keeping those decisions long after a user has finished the film. It is also stores aggregated forms of the users choice to “help [Netflix] determine how to improve this model of storytelling in the context of a show or movie.”
This doesn’t seem like a huge issue to me. This is standard analytics the platform keeps.
