My point is that having hundreds of millions of fans worldwide justifies, to me, that they're putting their talent to use in the correct way. I like metal a lot, Slipknot isn't even one of my favorite bands, but all the metal sub-genres just tend to blur and don't have much substance in my opinion. They're not the catalyst that TOOL or Pink Floyd may be, but they're still selling out massive venues worldwide. Whether or not their music is "easy to digest garbage" is your opinion, but that has nothing to do with their talent. They write songs that are filled with plenty of talent and people can realize that (With, of course, the exception of you and every other person who deems Slipknot as garbage).
