I think Netflix is the worst offender. If you spend a minute too long looking at the menu for a movie it will not only auto play, but for the foreseeable future Netflix will assume you’re watching it, want to finish watching it and watch similar stuff. More than most other services Netflix doesn’t trust your ratings or your lists when making up recommendations.
And yes, they had to get rid of ratings, because some people's feelings got hurt because they were being rated so low. Can't have that pesky objective reality rearing its ugly head.
