Malstrom has been on a crusade against Sakamoto for over a year now. What's funny is the narrative he's built up is distorting reality, and history. Malstrom has concocted a dramatic story - just the thing to rile up fanboys and launch a jihad - in which Sakamoto is an vile thief. Sakamoto swept in and "kidnapped" the pure and pristine legacy of poor Gunpei Yokoi, to pervert the memory of the dear departed. Malstrom and his fanboys have convinced themselves that Metroid was Gunpei Yokoi's "baby" and everything good about the series came from him.
In reality Sakamoto was there from the beginning and it was his ideas and input that shaped much of Metroid. Yokoi existed in the role of a producer. In fact, neither Yokoi nor Sakamoto were even the ones to design the character of Samus Aran herself (or the power suit).
I don't know just what's up with Malstrom's tactic and the hate train he is helping to steer (his ploy of claiming he is trying to avoid seeming like the instigator notwithstanding - when he spent months and months laying the foundation for angry fan tirades and giving them a warped story to use as ammunition). Malstrom is a character of the author; it's never been clear how much of the author's real opinions show through. Purely as a character, I'm not sure what overall goal the author has in spending so much time villifying Sakamoto. So I figure that the author is indulging his own fannish peeves, or has gotten bored and is truly being a troll - enjoying seeing how much hate he can whip up and less knowledgeable fans he can manipulate.
Oh, as for the guy on the previous page who actually asked how Mario Galaxy 1 could be defended for being such a "flop": in the game played by Malstrom fans who have taken his ideas too literally, a game could sell 50 million copies or more, one to each and every Wii owner, and if it didn't cause a single /new/ system to be sold, it would be "a terrible flop and utter waste of Nintendo's time".
In the Malstrom fan narrative, only new customers from the Expanded audience matter, or keeping present customers from this perceived expanded audience matters. Malstrom has built up a complex and layered narrative about the evils of 3D Mario vs 2D mario that is, itself, a genius construction of borderline insanity and nearly impossible to dig through at this point for people who swallowed it hook, line, and sinker. (The real points buried in it, perhaps intentionally, are smothered under ten tons of bullshit and an intentionally adversarial character.)
Nintendo attempted to make Galaxy 2 more "friendly" to people who bought New Super Mario Bros because some extra sales from those folks wouldn't hurt. But by and large, I think it's pretty clear that Galaxy 2 is primarily aimed at those in the core audience who liked Galaxy 1 and wanted more. The core audience has to be kept happy - and Nintendo stated such, several times, over the last few years. Statements that Malstrom and co. either outright ignored, or recontextualized. There's no way that Galaxy 2 cost Nintendo as much to make as 1, with engine technology complete, design tools matured, assets created, and the team already having spent a lot of time working on level layouts and elements that didn't make it into Galaxy 1. Spending a moderate amount of time and money making a sequel that would in the end probably sell at /least/ 4 - 6 million and keep the dedicated fan happy and the Wii out of the closet? It would be absurd not to.
Only in the mind of Malstrom fanboys who don't really care about the games, but are just in it for this bizarre industry-watching and speculating pastime is Mario Galaxy considered a terrible mistake that should never have been created and a sign that "NIntendo has lost it" or whatever.
