Facebook isn't a dictatorship. They're not forcing media companies to stay on FB.
If you're sick of FB, then don't produce videos for them. Don't use Instant Articles.
Going even further, delete your FB company page, stop posting FB updates, and stop buying FB ads.
Last I checked, media companies aren't paying FB in order to post content there (yes I know there are ads but media companies aren't complaining about ads).
What did you last check? Because actually yes, media companies absolutely pay social media companies large amounts of money for advertising partnerships, which generally take the form of "posting content" and "amplifying" it.
