I never really hated Obito; once it was revealed I thought his transition into a villain was amazing.

But what I was most mad about was how predictable it was:
 * Tobi is just a letter off from being an Obito anagram
 * Tobi only had his right eye visible, the left side of Obito's body was crushed
 * Their hairstyles were the same
 * Kakashi's Sharingan could teleport objects, Tobi could teleport objects (and himself)

We made the assumption that they were the same from the second he was introduced. But Kishimoto completely threw everyone off and said he was Madara, gave evidence to support that, then said he wasn't Madara, then revealed that it actually was Obito.

It's not so much hate for Obito, it's that Kishimoto didn't know how to hint at it without completely giving it away.
