#2 Former WWE Superstar Serena Deeb
Serena Deeb's WWE career saw her aligning with CM Punk and Luke Gallows as part of the Straight Edge Society. She was reportedly fired for violating kayfabe. She was publicly spotted drinking, despite her on-screen persona being forbidden from doing so.
In the era of social media, hardly anyone can maintain kayfabe. Hence, the company's decision to release Serena for failing to maintain a straight-edge lifestyle outside the ring was absurd. The current AEW star returned to WWE years later as a coach before migrating to Tony Khan's promotion.

#1 Former WWE Champion Daniel Bryan
In a move that led to indie fans throwing ties to the ring, the company released Daniel Bryan for being "too violent" on his main roster debut. The future leader of the Yes Movement was part of the debuting Nexus group, and he decided to strangle Justin Roberts with his own tie. This infuriated sponsors and led to his release.
The release turned out to be a blessing in disguise for Bryan. After three months, when he returned to the company, he was presented as a significant player. By the end of his WWE career, he gained more success than any other members of the Nexus.
