Didn't the slate team make a joke out of this concept some time ago? That was some good shit.
Anyway, altough I remain extremely sceptical of these things, I have to say: if the settings in those presets are transparent, I can imagine people picking up some techniques from it, so in a way it may not be so bad for AE's starting out.
But if it's just a preset called "Metal cool everything louder", that goes out of the window.
