No.
1. Sakura's haters tended to miss Naruto's overall arching point and tend to be simplistic in their desires for characters (cool, flashy op characters) and tend to fixate on her lack of a bust.
2. The Eastern fandom doesn't hate her as much as the Western one does. This simply means that there is something there that is unappealing to Western mindsets.
3. She's designed to be the normal one. As much as I feel Kishimoto cannot write women (by his own admittance), Sakura was designed to be the stable, normal girl in a very abnormal world. In Part 1 she probably feels like a fish out of water. Because the focus is on Naruto, we have no idea the personal trials she faces. She's also overshadowed by awesome (Sasuke, Naruto, Kakashi) and her feats are nowhere as "awe-inspiring" because saving several tens of thousands of fodder is consider dumb by people for some reason.
4. Kishimoto has repeatedly stated that he can't write woman doing huge things several times. AKA he cannot give people the Sakura they would prefer. Hinata would have the same problem if she was in the spotlight more. Her influence would be equally as minimal. Now I don't know why having a vagina makes you incapable of badassery for Kishimoto, but I'm willing to say this could also be the reason why Kaguya wasn't such a proactive villain, especially compared to Madara.
5. Kishimoto has stated that Sakura's representation of weakness is more geared towards "love". She is capable of unconditional love.Which is why she hasn't given up on Sauce despite the fact he's a single-minded idiot who refuses to learn from mistakes and thinks she can "fix him" or whatever. She's also a sixteen year old girl so hopefully, hopefully she'll grow out of the mindset.
I don't know if you've ever been in a relationship, but once in a while there are people who come along that you immediately want to help get better. Or maybe you get into a relationship with a girl and realize she has some issues, like social anxiety, rippling shyness, anything and start to think, hey maybe with this relationship I can really show her how to live so she doesn't have to be sad all the time. This mindset is really common. Do you know what breaks people out of it?
Experience. Sakura's currently in this mindset. If she hopefully moves on from Sasuke, she'll date enough people to see having this "personal healer" mindset in relationships can be extremely toxic to it and sometimes you can't force people to change. So as much as her confessions annoy mostly everyone, just recognize that she's an inexperienced teenage girl who's probably never been kissed or touched and she's never had to deal with relationships besides the one she fantasized between herself and Sasuke.
I hope this explained why Sakura's extremely complex (well, they all are) and people who "hate" characters tend to only look at them superficially and delve deeper into the characters psyche.
