I am putting that in quotes because I'm not entirely sure that I agree with the author's interpretation of events here.
In recent weeks, three key members of Anthem's lead development team have departed from work on the project, including Executive Producer Mark Darrah, Lead Producer Michael Gamble, and Lead Director Jonathan Warner, with only the latter intending to return to the game following a personal sabbatical.
According to a recent tweet from Gamble, the reason for this behind the scenes reshuffle seems to be Dragon Age shaped, as BioWare places the majority of its focus on getting Dragon Age 4 our of the door, following several reported reboots of the RPG sequel.
I can't find a source for these internal BioWare movements of the leads. These people didn't leave the company, at any rate, and this kind of movement is probably not uncommon after a product ships, especially at the lead level. Most likely the movement from Anthem to DA4 is unrelated to the state of the game as it is, but tying them together doesn't make BioWare look super committed to Anthem's future. I don't know if you need these specific people around to right the ship, though; BioWare hopefully has a gameplan for design fixes and it seems like the future stuff is probably in the hands of people who would've been handling it all along.
I dunno! This looks bad, but I think the headline might be a bit leading here. Anyway, hope they fix Anthem!
