Yeah, but I actually like multiple games built around blind boxes, and I sure don't like you telling me what I can like.
You're just passing your own tastes as morality and I don't care for that anymore when it's gamers pushing their preferences than when it was pearl-clutching moms and politicians trying to score cheap points.
I mean, there is plenty of justification for it in that blind boxes allow for a random distribution of items while still controlling rarity and allowing for balance, which is why every single videogame in existence that does any sort of randomized or widespread lootable equipment does loot tables. It's not just a very useful technique, it's a fundamental one you engage with constantly. If you want to make a case for monetization of randomized loot being beyond some line we can have that argument, but the method is useful and it won't be "figured out", it predates videogames altogether.
Frankly, it's not even the worst option out there. The sad irony of the entire moral panic is that the part that got figured out is an alternative monetization-to-engagement pathway. Several, in fact. Overbearing regulation of loot boxes is no longer a dealbreaker because everybody knows how to do seasonal cosmetics and battlepasses now, so all the features of paid loot boxes can be done without the randomized elements people latch on to.
The part you can't quite get is the outright advantage that loot boxes will sometimes give people decent stuff without having to grind, which all the current alternatives don't do. I'd take randomized tables over mandatory grind any day, but I certainly don't want to ban either.
