In a nice happy world, that would be true. Currently tho, its a good way to take out competition. (Tho why even take the time to mess with small games, idk as the money they gain prob is nothing to king who has made roughly $1 Billion USD as of December.... Seems like incredible greed.)
I'm far from an idealist when it comes to the business world. That being said, poor business practices like these shouldn't be tolerated with a shrug and an utterance of "Shit happens." Abusing the law shouldn't be seen as a legitimate business tactic.
Not only are they screwing over smaller games (honestly, no one would care about CandySwipe if it wasn't for this), they're attacking completely unrelated titles. I sincerely doubt that something like The Banner Saga, for example, is in any way drawing away players from Candy Crush Saga. They appeal to entirely different playerbases.
King's copyright trolling, for lack of a better term, poisons the well. They're damaging the entirety of the gaming market, all to remove some games that aren't even competing with them to begin with.
