Roku records and collects multiple screenshots every second of whatever you're watching, even if the content is being streamed from another device, and they analyze the images to figure out exactly what you watch, when, how long/often, and use that to make assumptions about who you are and what you're into which can then be sold to anyone willing to pay for it (and/or leaked/hacked). Maybe it doesn't matter much for the files you'd be viewing, but if roku could display PDF files they'd be doing the same thing there as well. Sadly, the more things roku can display for you, the more parts of your life they can siphon and use to stuff your dossier.
