It’s the same reason why
@NotATurkey (Turkey Tom) bent the knee and sucked the girldick when he originally covered Lucas last year. He knew he wouldn’t get AdSense shekels if he didn’t get the pronouns right and sweep it up for Lucas in his livestream chats. I will say that he seems to be going a little harder at Lucas with the last video or two he did about him, especially that one with the Elder Scrolls Morrowind NPC (Cheeto).
Whether or not YouTubers like Muta, WillyMac, or Tom would be more harsh if the “content guidelines” muzzle was removed would be just a speculation on my part. I don’t know any of them personally. But I do think that a lot of them seem to overcompensate and go beyond the bare minimum of following the rules to make sure their money isn’t being fucked with.
