Looks like the Axanar thing had an effect on one of the other fan film series.
From the Star Trek Continues fb page.
"CBS is not responsible for the decision to end the series. We are doing 11 episodes instead of 13 because another fan group took advantage of the good graces of the copyright holders forcing them to protect their property and the interests of their license holders. In deference and gratitude to CBS, we are wrapping up earlier than planned. We always have stood, and continue to stand, with CBS."
