I don't like ACR at all.. but after reading all the raging about ads on TVs I thought they would be terrible. Then I got one recently - the ads are literally just links to watch movies & TV series I might be interested in, on my TV? Like yes I do want my TV to show me some things I might be interested in watching, the same way Youtube does. I don't like the increasing privacy violations like ACR being used to tune those "ads", but seeing recommendations on my TV is a feature I like..
Heck if I had strong guarantees that the data generated by ACR was used only to tune recommendations/ads using an anonymous advertising ID like IDFA and not linked to any personally identifying information, I would want that too. But sadly there is no privacy and no way of ensuring that now.
Not everyone feels like that. Yesterday the app of my tv provider on my Samsung TV home screen suddenly shows a Prime icon in its place, prompting to install the app if you use muscle memory to control the TV. I am unable to remove this annoying ad. I really really hate ads and will go to great lengths to avoid seeing any in my private home. So I see this as an invasion of my privacy. Not buying Samsung anymore.
