This is going to be interesting.
Disney+ is now available in lots of places in the world. Many subscribers outside of the US will never have been to the parks.
And Data Protection laws in Europe and he U.K., for example, prevent them for using data collected from one purpose to be used for another purpose without specific consent. Just being part of Disney Corporation is unlikely to be enough. So using my purchases and activities at WDW or DLP to then influence my Disney+ viewing and vice versa without getting express permission could be a breach of those laws.
So they’ll need to think that through and ensure they get that consent or face major lawsuits from the Ombudsman in various countries under our Data Protection laws. And given they still haven’t managed to work out how to get to grips with EU tax laws I doubt their ability to do so here.
In any case it won’t get them far in our household. We have such different viewing habits that they’ll not be able to tailor anything!
