Me either. I have 0 problem with letting a machine seeing that data. Even if a human actually saw it I'm not sure if I would be bothered.
Edit: From the links you sent it doesn't explicitly say it sends screenshots. It sounds more like the ACR is run on device and then the result of that is sent to Samsung.
They are not saying they are okay with it because they have nothing to hide; they are just saying that they don't mind. It just doesn't bother them. And they also aren't arguing that it shouldn't bother you if you don't watch anything wrong or that every TV should spy on their owner.
