It is glorified gambling.

As someone who has played several of these (including HSR), the games themselves can be very good, but it’s always despite its gacha mechanics, not because of it. It should be obvious that gacha is a predatory monetization model that has unfortunately seen great success.

This has led to gacha games often leading the mobile market in terms of quality, marketing and development. I’d much prefer it if more games were sold for a one-time fee or even a subscription model for live-service games, but these types of games will continue to be rare in the mobile market due to the profitability of gacha.

On the positive side, most gacha games allow even f2p (free-to-play) players to keep up with the story and events. Many players even find playing these games as an f2p player more enjoyable because of the challenge. So for those who have self-control, I don’t think they should be discouraged from at least trying these games.

I played Genshin Impact up until I explored the world and beat a couple of bosses. As soon as it asks me to grind dungeons and pulls I dipped out. Gacha games suck, it’s always a massive time (or money) sink where you get almost nothing in return. Sure, I could spend a month grinding for that legendary character. Then what? I’ll beat one DPS check before getting stuck again and having to grind for the next thing. It’s surprising how many people pay money in these games and don’t realize how pointless it is.
