Bioware management doesn't get a pass for mismanagement of Anthem development just because EA is involved. EA bought Bioware in October 2007.
In that time before Anthem they released:
Mass Effect - 2007
Dragon Age: Origins - 2009
Mass Effect 2 - 2010
Dragon Age II - 2011
Star Wars: The Old Republic - 2011
Mass Effect 3 - 2012
Dragon Age: Inquisition - 2014
Mass Effect: Andromeda - 2017
Are you trying to claim that EA didn't interfere until we got to Anthem? Or even that it didn't interfere until the last few years before? Because that doesn't seem likely. If they were going to, they would have from the beginning.
