content id is a wild one that I only discovered a year ago: I had always used my own Chromecast when traveling, and I plugged it into a Roku TV which kept saying "did you know you could watch [content that I was currently watching] on Roku" which really freaked me out, so I looked into it. honestly not sure why they tipped their hand like that: I found the setting and turned it off. otherwise I would've been none the wiser.

creepy af though. the amount of tracking you implicitly accept by using random devices out in the world is staggering. even if you read every privacy policy and opt out of everything (I do) you have no chance.
