No one hated Sam Wilson when he was Falcon. He was the voice of reason, honest, and stuck to his morals. He was a true hero that should have been allowed to grow in his mantle. If you want the truth, the writers turned him into a completely jackass after Steve gave him the shield. First he tried dumping it on the Smithsonian, then was a jerk to Bucky who was going throw an adjustment period and lost his only friend, then treated John like a villain despite it being obvious John had serious PTSD issues and Sam use to council former military personal who dealt with it, then there was the lecture how terrorist had ever right to kill innocent people, and now he is mad Bucky has a Avenger team so he is suing. Personally, I like who Sam was when he was Falcon better.
