No one is forcing you to use Roku. Roku is honest and upfront about your info being the cost of the free service. Google, Apple , Netflix and Amazon are well in my opinion not telling you the whole scope of how they use your information.
You are welcome to cry and belly ache all you like. You have a choice accept it or move on and live in bliss ignorance that your data is protected by the mega corporations. I guess you do have another option to just live in cave avoid technology and hunt wild animals.
