80% of CG creators sure don't let the fact that they're talentless stop them from making comics.
I'd say the issue is more that making comics is comparatively easy. People in CG were complaining about the mainstream industry and a few of them decided "yeah, we can do better than that." Then droves of dummies thought that they had good and original ideas and decided to try it out as well. The Fandom Menace is in a tougher position because they were very specifically complaining about Star Wars under Disney. They can't just make their own Star Wars content. Even if they could, it would be very difficult. And even if they overcame that difficulty, it would probably be garbage. Because, as you said, these people are talentless. If Anna and Jeff Hicks are the creative powerhouses of your movement, you're in big trouble.
The thing is, Jeff Hicks pretty much did Stealing Solo on the encouragement of Frog, during the days when funds were being raised for such future masterpieces as Brand and the Cridious one and the Lady Alchemy one. Not sure what happened but he never really joined up with CG despite doing that comic kind of in parallel. He never promoted it as CG or joined the 'creator network'.
Anna pretty much did that Vampirella cover because Frog's Dynamite business partner was chasing her to be his spokestuber. Her JACK show pals kept telling her to do a comic (all of this starting a civil war that burned down War Campaign and thus accidentally saved CG from further decline) - but she was training as a concept artist, so again it's just her CG simps telling her to do comics, and her shrugging and saying okay.
I don't even watch Nerdrotic, after getting the feeling that he was a poser, but when I did watch him I saw him getting asked, hey have you ever thought about creating anything? He made a sort of half-hearted allusion to some ideas he'd had in the past, but it was clear he had no intention of ever trying to make them a reality.
Doomcock has even claimed to have done professional writing for comics. But he hasn't gone near CG, despite having good relations with Frog and appearing with him on the High Council.
What's the link between all these people and their lack of creativity?
It's simply that they don't want to, or need to. They make plenty of money just doing fuck all, making shitty Boobtube videos, reading out superchats like an electronic zombie muppet.
What's the point of doing anything difficult, if you can make plenty of money doing something easy. That is the basic reason for all these people trying to make money off of watching and talking about things, instead of trying to make money from the much harder activity of making things to be watched and talked about.
Of course there is always the "make your own sci-fi product!!" route, which would go effectively nowhere. These people want Star Wars. Most of The Fandom Menace haven't really matured past the age of 13 and just want more and more recycled Star Wars characters and scenes (despite their caterwauling about the EU). They don't want new sci-fi. They want Luke and Han blasting Storm Troopers ad infinitum. Look at how many of those faggots literally cried on camera when Luke showed up at the end of The Mandalorian. Regardless, I don't want those losers even attempting to create content. If I can be spared a TFM home movie equivalent of Magic Cop because these retards don't have the drive or spark of "creativity" to try to make their own shit, then I am grateful.
On a slightly pedantic point, I know there were gays who cried at the appearance of Luke in The Mandalorian, but actually that show did score a genuine 'not a dry eye in the house' moment with the Baby Yoda farewell just after that moment. Which yes, can definitely be called faggoty, but then it means emotions are faggoty, and then that means that the emotional emptiness of TLJ makes Rian Johnson a non-faggot and Jon Favreau a faggot, which I don't think is true. What I'm trying to say is, on some level all entertainment is faggy, like if it's not emotional then it's not really anything, right?
Anyway just to illustrate what I mean, here's a non-TFM guy who didn't like TLJ etc, but did like Mando, and you can see it's the Baby Yoda moment that really did him in, not Luke:
Mando was a legit success in the overall SW fandom, a lot of fans were like Frog and just blown away with shock when Carano got fired. This actually created a darker, fiercer 'menace' which you can see expressed in Frog's total embargo on Disney and his replacement of 'Star Wars fan' with 'Gina Carano fan' in his intro.
