Even though Zenimax Online will create the game itself, Bethesda did allow them to use their franchise without copyright striking for using the word "Scrolls" in the game. (Ehm, ehm, attempting to sue Markus Peerson for attempting to create a game called "Scrolls".)

I'm rather interested in WHY they'd let Zenimax take this game title, and create a game which differs from the series.

Plus, I believe that Bethesda does help in creating this game, due to the fact that they storyline itself will be created by them. I don't expect Zenimax to create the 2nd Era storyline by themselves, but ask Bethesda to use their history books. (Unless they consult the book of knowledge of all Tamriel: This wikia.)
