Just because it makes the majority of vocal people whine doesn't mean it's a bad idea financially, for all the whining for every Three Houses banner there is, it's a financial success, Meanwhile, for example, Ashera banner was received with warm comments by Reddit communities as well here, but financially it flopped. And for companies it doesn't matter if you say you love it, what matters is that you buy even if you complain it's bad later. These vocal people are the same as the one who complain for spam of latest games, ones that actually makes money, and yet didn't bother to whale to show older games show. You support them by whaling in banners, not commenting on their twitter accounts. And we know in most gacha playerbase, the players are silent, that they don't feel the need to express their joy of playing the game with words online (as their money already did)
There is Genealogy? Sure, because Japan loves Genealogy. It's a fact that Japan are more willing to spend in gachas, that to make this point, last year FGO makes 24 USD million overseas, excluding japan, when it makes 248 mil in japan only. Sure, when it comes to FEH, the japan only revenue is 66% , not as extreme as FGO's 10x compared to global, still, point is, if it makes money in japan they will still do it.
as for the leak itself:
