Why is Bidou getting so much praise and attention?

After being told by smash 4 players that wave dashing and L-canceling are "glitches" and "ruin the game", I feel like Bidou praise is the biggest hypocrisy I've seen in this community. Bidou was NOT intended to be in this game, and there is no logic as to why it happens besides bad coding, so why are people treating it like it's the best thing to grace smash?
