Well... personally speaking while I like to draw, I mostly do comics because it's like doing a long term commission and I need the money, while at the same time of course I work in stories based if I'm interested and it's on my abilities. I don't think that any of the stories that I work for is going to be the best next thing, or that we'll get famous or anything, that's asking for quite too much luck and sometimes, a lot of attention can be exhausting. I know, with more views you can even increase someone's pay but while I don't call myself a pessimist, I would say I'm realistic, effort and passion doesn't always guarantee life-changing success neither stucking with the popular on demand things, because just like you, millions are jumping into it everyday.
While I don't deny I have a few stories of my own, I'm not interested enough to turn them into comics, and if I do, I would probably do the first chapter and leave it forgotten for around a year or more.
What I see first is that a lot of people are not only hungry for attention, validation and compliments. But what I can tell is that they also seem to be from... bubbles, where they are a peculiar individual who exceeds in a talent inside that bubble or social group, however, once they begin to interact or to finally go beyond what they've known their entire lives they get frustrated because they notice they aren't actually especial... but another one of a majority that they didn't see nor knew about, and that's upsetting.
You also have, among those individuals those that are not used to failure or that things don't go the way they desire, therefore, they are very analytical about what to do, and since they also have a narcissism and quite the people pleaser behavior (But of course, with the goal to obtain recognition and receive once again that feeling of being unique) they try to do content focused on popular things because they believe they'll succeed with that (And that honestly, that's not true, with popularity also comes competition and overload).
The goal may vary from one another, some want popularity, increase their numbers in one form or another (followers, likes, views, comments, etc), self-steem, validation, have a "not-failure" comic to be proud about to later presume on portfolios (Prob to get better jobs, recommendations, be hired by a company or person, etc)
The only thing that I still gotta mention is that whenever some of these... superficial goals is not met, you'll have this people asking if it's better to cancel their story or abruptly finish it because "it's being ignored, I love my series but people not caring about it hurts me so much" (And this can be because of the art, the flow, the style, the genre, the execution, characters, etc, anything that may be the thing that is not working, even promotion)... And honestly, my mindset is quite simple, if you tell a story you gotta ask yourself why, it is for yourself or for someone else? And if you drop it... then, I think you didn't love your story enough if you have to ditch it away because it's not bringing you desired results.
Sometimes people have too much ego, or believe that just because you do Isekai, BL or NSFW you're going to solve all your problems and gain a lot of money, while the reality is that there is a lot of competition, a lot of times you need to produce more than what you're capable of just to get noticed or to get paid faster, or the harsh reality is that it takes years to build a fanbase to then have less than 10% of your followers to actually support you.
