Well...exactly. The vast minority of players are going to go on to internet to find out how to excecute these techniques, and it isn't taught in game, so the people who do nerd out on the internet and sit learning them will be spoiling the game for others. As you put it, it needlessly "takes their fun away", which is why I find it so crap. Atleast for snakers, again, as you put it "it's a cheap technique that ANYONE" can do. Hell, they could even learn it mid-race and make a glorious comeback.
Relevant quotes:
"Advance techs are much harder" (Pretty much impossible to discover yourself without extensive outide guidence)
"Ruins their fun" (Great, selfish bitch :p)
"Snaking is easy." Exactly.
Just to set it to vibrate and finish you off, by this regard, snaking is much less cheep than Smash's harsher equivelant.
