Paywalling is hypocritical from the start because these creators are using the HF patch (free, fanmade), the xukmi shaders (free, fanmade) and the KKUS/KKUTS shaders (free, fanmade), use scenes to display their character (yes those too) that use the Conquestus furniture, accessories and maps mod (you guessed it), using most QOL of life mods that allow for easier use of accessories and character creations (yes those are free too)Paywalling also increases the quality of cards (with some notable exceptions), so I don't really get the hate
Hell, they probably use a pirated copy of KK to boot
You're basically building your paid content off a mountain of content that was made for free by your predecessors for years and years
If KK still existed in its original form and none of those mods were accessible, their own content would not be possible.
If they had to pay for all of the mentionned above, a paid content creator would themselves have to pay somewhere in the range of 500 to 2000 dollars worth of licenses and subs a month to have access to all this content
They couldn't make any of their content in those conditions
Asking for compensation for private commissions would be ok, so is doing like Yurabe where your content is free and you just ask people to support if they can.
But the current status of paywalled content in Koikatsu is doing more to discourage people from getting into it or to keep making content in it, since every time something cool or a really nice character card comes along, you have to pay for them
