Lina Khan is the FTC chairperson. The FTC regulates monopolies, so it can be said Lina Khan regulates monopolies. [Assumption by the FTC] Apple is a monopoly.
Based on this assumption we can say that Lina Khan regulates Apple (and others).
Apple did not want to produce an episode of a show which might mention Apple (or companies like it) in a negative way. This would likely have happened because the FTC has increasingly focused on tech monopolies.
Is the headline really that wrong? The fact that we publicly learned that Apple didn't want to produce an episode featuring the FTC chairperson is what is referred to as censorship here. Of course that is simply editorial control by the producers - but it does feel like a protective move, retaliation or something in between.
I don't find the story interesting (no company would produce content which could make the company itself look bad), but I do not believe it to be wrong as you allege.
