Because it's brainwashing 101. I'll keep reminding people as many times as I have to until people get it that this is what they're trying to do. To brainwash people, you have to inundate them, bombard them 24/7/365 with "the message" and give them no relief or no alternatives that don't preach "the message." Every piece of media the subject consumes must preach "the message" so that eventually they'll just instinctively repeat/regurgitate "the message" themselves. If the subject has access to anything that doesn't preach "the message" or worse explicitly countermands "the message" then the brainwashing could fail completely.

That is why the Woke literally do want every book, movie, TV show, and video game to be Woke. It's so that their lies and propaganda are seeped into everything and we have no escape. Make no mistake though, it's not us living now that they're focused on. It's future generations. They're playing a longer game. Kids are going to grow up in a world where their media is woke and they'll grow up believing that wokeness is normal. It falls on us, the non-Woke to fight against and defeat Wokeness NOW before it's too late.
