How is a choice a "hidden" oppression? I can see an argument for algorithms suppressing certain world views being a problem...but as just a stand alone choice, that is not real oppression. If you think it is, you've probably never lived in an oppressive country. China is essentially stack ranking citizens for access to certain rights and you're concerned about people's viewing habits. We've gone generations of people claiming the same things about radio, TV, music, etc. In the end those were replaced or the next generation wasn't as attached...actual oppression is sticky.
Is it a choice if that things goes to great lengths to take advantage of you by manipulating known triggers in your human behavior? Some people don't have the will to choose, that's addiction.
In the long term I'm not so sure that your statement will stand.
