Big Roku fan here. Was an early adopter, have had many versions of the device over the last dozen years and been a brand evangelist to my friends and family.
I also try to avoid being a panelist in behavior datasets. For this reason there are financial planning services I won't use and I won't buy a Vizio TV.
So, I'm very curious about your assertion that Roku is doing analytics for sale. I hadn't seen that before, so any further insight would be appreciated. Thanks.
