Of course they had to name a film making proprietary tool with the name of an award winning film made using open-source tools released less than a year ago...
"Flow" is one of the most generic names in tech. I can think of 10+ products called that off the top of my head.
There's no way they named their AI filmmaking tool after the last winner of the Academy Award for Best Animated Feature by accident.
I still remember a style transfer paper which proudly mimicked a popular artist who had passed away barely a few years before (Qinni). Many AI researchers seemingly want to wear the skins of the people they rip off.
Seems pretty obvious that they named it after Facebook's JS type checker from 2015
