They already have one where the put most of the prime games called “Amazon Games App”. So if “Vapor” is something new it is more of another another launcher.

If they however just update the game app to also be a store front, it be fine I guess. I’m not thrilled about everyone needing there own launcher, but Amazon already has one, so can’t really blame them for spicing it up a bit, to be at they other launchers level.
