Don't let it get you down. All this does is assert that Kishi isn't a great writer, and that he has no respect for his work or his fanbase. You shouldn't feel bad because Kishi and his editors turned out to be a sexist pig with below standard morals. No matter what that interview said, it proved that he wasn't thinking about NH and SS a long time ago, else we wouldn't have had l those moments, and there would have been development between Naruto and Hinata.
Continue to have faith in the REAL Sakura, i.e. the Sakura that didn't take kitten from anybody, the Sakura that had self-respect, the Sakura that appeared before the atrocious ending.
If you're looking for manga to read with great stories, characters, and authors that aren't scumbags, I suggest One Piece, Fairy Tail, Bleach, Akame ga Kill, Magi and Attack on Titan. I'm also reading Ao no Exorcist, it seems to be pretty good as well.
And the real Naruto, who won't give up and won't take back his words, and who loves Sakura truly.
I believe Sakura won't be like in chapter 699 whose self was 12-year-old again like her developments were nothing.
