This could lead to real Play Store competition. I think that's grand. I'm familiar with managing multiple app stores because I'm a Samsung user and there's been an integrated Galaxy Store on every phone I've had going back at least 10 years now. There's nothing wrong with the experience. I've still got the Play Store, which is front and center, presumably because Google is making it worth Samsung's while. I've gone back and forth between having apps installed from one, both, or the other only and right now I'm on Play Store only (but Samsung's Android skin, OneUI and various Samsung apps and services update through that Samsung path.)

This is not a big deal. Multiple or alternative stores should be the norm, and celebrated.
