So you have internal information on what happened? Please share.
I shared some internal information about Patrice's and Jade's roles inside Ubi plus some of their other projects and CVs in post #58
in case you're interested. Jade started as programmer, then was producer in several hits and she was tasked to create and lead Ubi Toronto, which became Ubi's 2nd biggest/most successful studios.
With she as producer or studio manager her team worked in over a dozen super successful games including some of the 'recent' biggest Ubi new IPs (AC, The Division, Watchdogs...) and some of the most successful Ubi games ever at their time. Then EA hired her to create and lead a new studio, Motive, that did help on Battlefront II and later made Star Wars Squadrons and the Dead Space remake. Ubi, EA, Google or Sony hire her to create and lead teams because of her long an successful career building and leading teams who produce big hits, not because she is hot.
In AC Patrice was the creative director (not the same than a game director, I explained in that post the differences between the roles in the post and also the differences between his and her roles, I worked at Ubi but not with them even if I met them personally). He and she had a normal relationship, the issues he had with other Ubi staff were in a separate project where she wasn't involved.
