You can disagree with the site he is hosted at (and there are many very good reasons to do so), and also have issues with his Twitter presence (then again, personally I'm of the opinion that more we disregard Twitter the better of we are).
But the fact remains, he does have connections within the industry that while may want to remain anonymous, give some good insight into what really happens. As an analogy, his piece on ME:A was terrific (or terrifying, I suppose it's a matter of perspective). Attack the message, not the messenger; personally, I'm going to read it once I'm done with the more mundane aspects of my daily life for today.
Indeed.
Just because Jason is demonstrably wrong on many topics, that doesn't render his investigative journalism automatically worthless. Facts are facts and if he's been able to dig them up, kudos to him.
However, given the lengthy quote already provided, I suspect his angle is how heartless corporations opress and exploit. So let me bring you up to speed, Jason:
1. Without capitalism, video games would not exist, The gaming industry would not exist. Heck, videogame journalists would not exist.
2. If Bioware employees were or still are dissatisfied, they can discuss the situation with upper management and ask for a change, they can unionise, negotiate. They can go on strike. Or they can simply leave and join some other better suited company. Or they can start their own company, for that matter, spending their own money the way they see fit. However, they do not have the right to dictate how others spend money. That they certainly do not have.
3. Apparently, some decided to leave. Those who after consideration decided to say must have had no better option. If they had no better option, with whom does the problem lie?
