Again, that's saying that Smash should be the only game of its type. The market may not be able to support a game that feels like Smash, but then, when do you start? Should Smash stay as the only Platform Brawler? That's like saying that Street Fighter should have stayed as the only 2d Fighter game, as it was the only one that was really "Popular" in the 1990's. Then came the sequels and spinoffs. What makes it different here? A popular game, one of the few in its genre, can't have other games like it?
Your comparison with Bioshock also doesn't make sense. If a game is literally the same thing, with the exact same combat, story, setting, and theme, then it's a ripoff. All Stars has a common style, but it's pace, way to win, characters, settings, and different ways to fight makes it more like a Spin Off than a Rip Off.
