I don't think the writer read correctly what Adelman said.
What he was trying to imply is that Nintendo should back those publishers who actually try to utilize HW advantages and also to show people that those games are on par with Nintendo's own titles.
It's a matter of helping developers take a risk and communicating the quality of said game.
Nintendo also wants exclusive games on platforms and not just ports on all platforms. But we don't live in a time where that is possbile anymore.
You do need ports, especially if you get versions of the hit titles that month afer month, year after year, dominate the charts worldwide.
And that is something the writer kinda talks about but then doesn't make the necessary conclusions: it's true that 3rd parties sell the systems probably more than the actual 1st party games by MS and Sony. And if that happens, if those games are exactly what consumers want the most, if you don't have them and your exclusives are nowhere near those type of games, than you won't succeed. It's that simple.
What Nintendo needs to do first is try and make those type of games so that developers have a market to sell their own games and not the other way around. No amount of ports will help create a market on NIntendo's HW.
If they can create an ecosystem where for every MK, there's a Forza/Gran Turismo, for every Zelda, there's an Uncharted, for every Xenoblade there's Final Fantasy/Dragon Quest, etc., etc., then developers will have a place for their games and gamers will realize that they can not only play their ports, exclusive games of their liking and the next Mario, Zelda, DK, MK, Smash, etc.
To me, that's the path Nintendo needs to follow or they will never get out of distant 3rd place.
