In the wake of last week's blowup with Improbable over the use of the SpatialOS cloud platform in games built on the Unity engine, Unity has once again updated its terms of service, this time to state explicitly that developers are free to use any third-party service they want. CTO Joachim Ante said in a blog post that went up today that developers using Unity own the content of their games and "should have the right to put it wherever you want," and acknowledged that the December 5 TOS update that started the dispute with Improbable "didn't reflect this principle." 

"Our TOS update on December 5 was an attempt to define what our terms mean for the cloud and an opportunity to make our business model clearer," Ante wrote. "After listening to developers, we realized how this language came across, and how it would impact your ability to choose."
