Don't give viewers what they want; instead you should show viewers your bullshit politics and disgusting sexual fetishes.
For example, you should cast a gross transsexual like Oliver Lennard, even though nobody wants to see him.
I really do not understand Bob's vehement hatred of the audience. He seems to relish in the thought of fans of a property getting shit on for no reason other than he has a spiteful hatred of everyone else (but don't you
dare tarnish things
Bob likes!).
Now, I will concede that fanservice can be overdone. It's like the frosting on a cake, it's a nice addition but too much of it and you get sick. I'll also concede that you can surprise fans with something they didn't even know they wanted and make something even better. But why is it a bad thing to want a series you've enjoyed to stick to what you love about it? Some fan ideas are bad, but some are a no-brainer, as that first tweet that Bob is mocking showed. At no point in the Disney Trilogy did the old band get back together, which would have been a big "I clapped when I saw it" moment that Lucasfilm utterly failed to capitalize on. Instead, they only ever had two of them together at a time at most, and they killed off nearly every legacy character unceremoniously (although Carrie Fisher's death forced them to bump off Leia).
And this is apparently a good thing, according to that last tweet, as we're supposed to enjoy watching our favorite heroes be turned into sad sacks who have failed at everything, requiring them to be replaced by a girlboss who's way stronger and better than those old characters could have ever been. The reason why this is good is not explained, merely stated as fact. Even if you wanted to argue that exploring the concept of an old and tired hero is worth doing, you can't reconcile that with the incessant need to belittle, degrade, and replace them.
As an example of how to do this right, let's look at Logan. It's a grim time for mutants, with most having died off and the rest in hiding. Logan's getting old and his body isn't in the shape it used to be, and having to care for an increasingly demented Charles Xavier isn't helping matters either. He's not in the position to be a hero anymore, nor does he want to be. But when circumstances force him to, he steps up to help a girl in need, sacrificing everything to get her to safety, even his life. Despite being confronted with his previous failures to protect those he cared about, he's able to overcome his doubts and prove that he can still be a hero. He's not denigrated by the script, he's shown to be someone who's simply been beaten down by a rough life yet manages to retain his heroic core.
Contrast that with Luke's portrayal in Disney Wars. After RotJ, he barely starts scraping together a new Jedi Order before he gets some premonition that Han and Leia's son is going to be evil, so naturally he takes the smart path of trying to murder him in his sleep, totally not out of character. Then everything burns down, he runs away to be a sad sack for years, only for girlboss Rey to show up and bitch at him for being a failure. When he finally does get off his ass, he doesn't do anything in person, merely Force project over light-years to be like "haha pranked you" to Kylo, the effort of which kills him. He doesn't get to redeem himself, he doesn't get a happy ending, he's just killed off in an unsatisfying way. To call that a better version of Luke than the old EU is ridiculous, where he had a smoking hot redhead wife and a child, successfully brought the Jedi Order back, and helped fight numerous battles against the Imperial remnants and the Yuuzhan Vong, all while keeping his character intact.
I'm rambling, but to summarize, Hollywood sucks and Bob's a contrarian retard.
