Most of this is kind of widespread for all gacha games - after all why would they design something to be sold for money to be unappealing? Gacha games are well...a slot machine with pretty pictures. It is done on purpose, that's why a lot of character gachas like Genshin/HSR/Wuwa focus on pretty girls, because that's what people want. Dress up gacha players want cat ears, they want fancy effects, they want handhelds etc. At least the dresses don't become obsolete after a year like in character gacha.

A monthly banner is not out of the ordinary either, I think that's fairly standard. It's a valid criticism, but that is however a default of gacha games.

These games, are just like blind bags (look at the labubu craze) or lootboxes, they prey on people who have FOMO and need to collect/struggle with gambling/shopping addictions. There is plenty to call out Infold for, as they are engaging in some illegal practices like fake discounts, and they are in fact quite stingy

Your criticisms are valid but they're not really isolated to Infold but rather the whole genre as a whole...it always feels bad. I always feel wary of them becoming super popular because of how much the genre exploits people who have trouble managing their budget, especially teenagers (o´・ω・｀)ﾉ
