Gacha can be moderately acceptable if the math is fully documented and enforced. If you know it will take <= 180 pulls to get Raiden Shogun, and each pull costs $3, then it’s just a $540 DLC with extra steps and the tease thst it might be cheaper if you’re lucky or have banked pulls.
But transparency is key-- the developer should be expected to offer a calculator or lookup table for any RNG item, especially if it’s some combination of multiple drop mechanics or hsrd-to-convert currencies that dissuades back-of-the-envelope estimates.
Even in Vegas, the slot machines are required to disclose their payout rate.
There’s also significant differences in the gacha appeal factor. If there are no leaderboards or PvP, and the game mechanics can be completed with F2P only, that is inherently less pressure to spend then on a game where you regularly get your ass handed to you by a someone with a Black Amex and all seven-star limited banner units.
