Have you looked at the list of studios - big name ones, like Visceral - that EA has shut down in the past? EA absolutely will close BioWare down if they decide they aren’t profitable enough anymore. Look at how many of BioWare’s substudios they’ve already shut down (BioWare Montreal made the Citadel DLC. Then they made Anthem and POOF, now they’re gone), and all the layoffs they just announced at BioWare Austin and how they’re shifting SWTOR to a completely different, outside studio.
