Yep - it’s a good thing they just IP block users in ID check states or this could have been REALLY bad.

This is a VERY interesting thought. I hadn’t considered all the data collection likely available to Google as a result of the casting protocol. This is definitely plausible.

IS IT extra code to maintain though? My understanding of casting is it effectively sends a URL to the receiving device. I would think there’s a negligible amount of development spent on maintaining it. And every media app under the sun supports it, now except for Netflix. 🤦
