I agree with you. That is why in my head, they're was no doubt it was the endgame. That's why I felt cheat,screw and rape by this ending and why I am pissed off. Sadly, NH and SS just cried victory and call us stupid because we know how to read. They don't consider this asspull and use the movie as an excuse (though developing a love story about 2 character who didn't have any interaction is still asspull, but they never acknowledge that and we're the idiots on the net)
I left NH right when I started reading the manga, and watching slextrem and lordofice72 videos. When I realized that I really couldn't counter their arguments, that's why I felt like something was wrong. What was filler and canon and what was the difference? That question made me go find the manga and read it and I was amazed at how wrong I was, even about Sakura, because she isn't as bad as the anime make her out to be.
I've actually seen NH and SS fans call BS on this ending too and I was surprised, because I always thought that all they cared about was seeing their pairing win.
If we're the idiots on the net, then literally us, and even the non shippers, other shippers and sns shippers are also idiots then, because I could swear even up to 699 Sasuke didn't love Sakura..in fact, 699 was probably supposed to be a SK moment.., and in 699 Naruto doesn't even interact with Hinata, yet in 699 he still refers to Sakura as "Sakura-chan" and she completely ignores him..wtf..they didn't even talk..she just arrived there and ignored Naruto's existence..my gosh...she called Sasuke stupid..that didn't even seem right...ugh...my gosh :/ ..
