"In the same way that if you are against Elon Musk, you boycott or don't buy Tesla"
Yeah that seems to be effective. He's down to his last trillion.
Re gaming. For the past 15 years games development, communities and marketing was dominated by these kind of TRAs and trans identified guys - porn-addled neuro divergent, tech geeks. Then after lockdown's gaming peak, consolidation and AI led to around 25-30% of jobs going (this is on the back of big expansion prior to this) and many of these activist employees were first out of the door. This coincided with the massive success of Hogwarts Legacy and gaming becoming more female and mainstream. Many games leaders breathed a secret sigh of relief about no longer having to deal with them. The film industry is currently going through similar and that's why his kind of work can't get greenlit.
(Not saying that unemployment is good but the vagaries of film/music/gaming markets mean that there is expansion and contraction in employment. Nobody chooses a career there thinking its a job for life.)
