What transpired between Michael Bay and Megan Fox in the Transformers franchise?

Why did Megan Fox vanish from the Hasbro franchise?

 

Despite the magic of filmmaking that Hollywood casts upon the industry, behind-the-scenes machinations of some of the most popular and renowned creations are often quite nefarious. As a commercial enterprise, protecting the bottom dollar leads to morally corrupt practices and rationales in Hollywood, starting from pre-production to distribution. Even as the media and public are expected to be more perceptive of unethical business strategies, the Hollywood system is still dominant and influential enough to bully their way toward their goals. Routinely, it is the movie stars on screen, the people that drive customers to theaters, who are most punished by murky practices. In the 21st century, one of the more unnerving controversies surrounding the treatment of an actor involves Megan Fox‘s fallout with director Michael Bay and the Transformers franchise.
