All business are "in the business of making money", that's what being a business is. What sets them apart is how they make it. In the case of media companies is, precisely, by getting the story right. A publisher that doesn't is more likely to lose influence and readership as time goes by. For a publication like Bloomberg, more so.
So yeah, they do care. That doesn't mean they don't fall for scams or bad reporting. They do, but it's in their best interest not to do so. In this case, I'm sure Bloomberg is already frantically calling all the reporter sources. They should have done it before the piece was published, sure, and they'll sure blame the reporter and the sources, but I think it's disingenuous to think they just shrug these things off.
