For now, yes, I think that people would calm down, but honestly, this reaction from creators seems to be a symptom of a much deeper problem
I agree with @devika s response that
even before the app was created, creators seemed to still have a fair amount of difficulty promoting their comic on the site. It may have been frustrating and all, but I feel that creator apprehensions really ramped up with the release of the app. the app primarily consist of A) paid comics or B) extremely popular content (maybe 20ish series). With all of that relegated to the front, and trending and browse all (the main ways the majority of creators get seen) being not really easy to access (you have to click through at least one or 2 pages to get to them) nor having any flashier colors to incentivize clicking on it (like the trending tab looks similar to all the other tabs in browse all, no more importance is brought to it through design or color unlike banners present on the front page), promoting a comic on a platform that was already tricky to promote on just became a lot harder.
Even after the app came out though, at least there was the website which remained relatively unchanged, but after the new update, I think the reaction that came out of trending/popular being moved to the bottom of the front page was a result of seeing a trend where promotion is becoming an increasingly difficult task and for fear that this trend will continue in the future.
Honestly, I don't think too many creators have a problem with the paid for content being part of taptastic, but to me, the ratio of paid/popular content to everything else is a little alarming. There's tons of categories for paid for content including top books and tons of collections, but rather few for the majority of creators (pretty much trending and browse all are it). I don't know if it's the same for others, but I can't help but see it as "there's pretty much 2 categories that help promote the majority of comics and yet all of them are buried under other content. How hard can it be to promote just 2 categories?" If you bury those two underneath everything else no one will see it, yet if you promote those two they take up a pretty small space, they're just 2 after all, and anyone that looks at the app for more than 5 seconds is still going to see all the other promoted content. I mean, i'm not an app designer so i'm sure there's more complexities to making a website or app than I think, but i'd be lying to myself if I denied the sentiments I expressed previously.
