If you could take over an entertainment company or an IP and do something petty/out of spite like they have done (for example, 2016 Ghostbusters which was a middle finger to real fans or Disney throwing out the EU only to bastardize it). What is 1 to 3 things you would do just to return the pettiness or for revenge?

I would do the following:

Make the Rey "Skywalker" movie and have Rey give up on everything and become a grumpy hermit just to see the critics/shills twist themselves into knots explaining why that was brilliant for Luke but sexist for Rey.

Hire someone to actually adapt Wheel of Time and cast people who look like they are described in the book so I could sit back and laugh at the wailing and gnashing of teeth.

Take over a company that makes romance novels or romance movies and have all the male love interests be balding, overweight, middle aged men who are unemployed. When there is backlash I'll just lecture the women about body positivity and unrealistic expectations.
