Because customers prefer original games from casinos with a classic look, rather than from providers with poor game design (this is just my opinion).
Since Casinopunk is still a fairly new casino and they have just introduced UI/UX changes, who knows, maybe in the future they will develop more original games.
Honestly, I rarely play "original" games for a specific casino. Mostly, I play specific providers that I can find in any casino, without any issue. As long as I don't face any issues and I like the general environment of the casino (promos, bonuses, etc), I will play there. Whether they have original games or not, doesn't matter.
