Because ZUFFA is the real boss, not Dana. When Dana tried to axe Fitch for not giving the UFC a video game exclusive, Dana's decision was quickly mediated and Fitch was brought right back.
If you're a revenue producing fighter in any capacity, ZUFFA wants you around. If you're a no-name fighter with zero revenue generating power and Dana axes you, then that's just real life. In a giant company, you're worth what you can produce.
Fitch is different when i refer to fighters being axed im not speaking of the Top guys the elites im speaking of the Duffee's, cut because of their "ATTITUDE" after one defeat.
