He won't admit Mewtwo is DLC, and he has stated in the past that is was ruining the industry. I wouldn't exactly say he's in support of it...
To be fair, we haven't yet confirmed that Mewtwo will be paid DLC (or if we have, please correct me), it could be an early bonus for people who got both, and get patched to everyone later.
And besides. If we heard ten years ago that we'd have to pay five dollars for a reskin for one character, we'd have near-boycotted a company for that (not literally, but that was the attitude). And these days when a dev offers an "expansion pack", people are constantly debating whether it's an expansion's worth of content or if it's just overpriced DLC.
The reasons some people are giving on here are absolutely ridiculous. Yes Sm4sh is its own game, but that doesn't mean it can't have a mode offering a different gameplay style. Especially if that mode is a completely optional DLC. Who cares about community splits? Is it wrong to let people play the game the way they want to play it? Before you tell Melee fans to go back to Melee, think for a second. You enjoy getting new smash games. Why would Melee fans not? They want the new characters, stages and features too. They don't want to keep having to go back to the old gamecube forever.
The real reason why this DLC would never happen is because not enough people want it. Melee doesn't have a big enough fanbase to spawn a DLC that Nintendo doesn't want. So stop making this about Melee vs Sm4sh.
Generally speaking, all of the Melee fans I know just want an HD Melee remake, not a new game with Melee's mechanics. After all, if it's not identical, there's re-learning to do, and that defeats the purpose of a six-character viable roster.

That's the best argument, really. The demand isn't big enough. Most people who like Melee own Melee, or have pirated it and thus proven they really don't want to help Nintendo in that regard anyway.
