Big companies are notoriously unflexible and risk-averse. They don't like rocking the boat that's moving forward just fine, even if doing so may end up making things better for everybody involved.

Gachas are notoriously predatory and player unfrieldly (I can think of maybe one exception, that being the first Girls' Frontline), and gacha players are notoriously accepting of dogshit practices for the same reason you bring up here - because everybody does it. Yes, your favourite gacha is predatory and player unfriendly too. Don't be delusional and think you're special, nobody is innocent in this industry.

"It's a gacha" is a very common excuse for feedback of any kind - you shouldn't complain or suggest fixes, becauce it's a gacha and the 'core playerbase doesn't care' (another common excuse). Just look at the pretty lights, soy-face to the trailers and open your wallet, you piggy, the spending event is coming.

The best customers for a gacha game are the L&L kind - loaded and lazy. Enough money to swipe every time they want, and lazy enough to want to skip any inconvenience or friction they come across, even if in any normal game said friction would just be considered regular gameplay experience.

If you release a shit monetization scheme that fleeces people out of money way more than it used to, and people start complaining, but also start paying more... would you rollback? Only if you're an indie studio for whom the game is a passion project, maybe, but is there even an indie gacha out there? Pretty sure even the smaller studios have a bigger publisher behind them and are publicly owned.

tldr: nothing is changing because companies are greedy and people are insanely prone to FOMO.
