How can people hate TNA for signing former WWE wrestlers when WWE did the same thing to build there company?

Because they have no knowledge of WWE doing that..i will say that WWE did make superstars better by bringing them to their company..think about it, WWE created Stone Cold Steve Austin and made him a household name..same with HHH, Kane, The Big Show, Lita, Rey Mysterio and Booker T..they just improved the identity of the superstars..WCW made them big, WWE made them BIGGER..when TNA signs superstars from WWE, WWE has already established them as great superstars and people hate it because they say that TNA is stealing the WWE's creations..people hate because they say that TNA should have their own homegrown talent..it's just a topic that can be debated back and forth for hours..
