I merely said that the domestic Japanese fanbase was one thing, but even if it does have more of an NS fanbase, SP clearly didn't care about that.
SP was always looking far more at what the international fanbase preferred (a much greater number of fans to look at which means much more money to make compared to what they'd get from the Japanese fanbase alone) and, unfortunately, a lot of the international fanbase APPEARED to prefer NH over NS (though there have been reports that SP blatantly lied about various poll results and such to Kishi to convince him to change the pairings). Whether that's true or not, SP grossly underestimated the international market as there were a lot more NS/SK/SNS/logical neutral fans than they expected and also underestimated the logical capacity of a lot of NH/SS fans (fans who like the pairings themselves, but still have the logic to know just how badly they were brought about, and how bad they still are, in the story and so still hate the ending and things that followed because of how terrible it made the characters look, and by extension, themselves as fans of those pairings).
There's also the fact that images, videos, and reviews of The Last were hitting the Internet and spreading quickly right after the first showings and so SP also lost the element of surprise in the international market compared to the domestic market, where they were able to trick people into pre-ordering tickets with misleading marketing and advertisements, then preventing refunds when the truth is revealed, since they already knew what the movie entailed.
Such reasons are why, compared to the money made in Japan, The Last completely failed internationally and, as a result, SP actually lost more money than it gained overall, or broke even at best, which still isn't good for all the marketing done, and all merchandise that was made, but didn't sell, and that overall failure is why SP has been trying so hard to make Hinata look irrelevant again in the story by barely giving her any page/screen time or anything, as well as trying to blatantly attempt to "reset" the story through Boruto. They're hoping people will eventually forget...but we won't...
It's exactly that point. Not just SP but the entire Naruto staff from Shuiesha and SJ thought that the international market would bring the millions by catering to the western NH fanbase. It took two canon films internationally surpassed the the RTN international earnings. Pathetic.
