It's not really the same as a bazooka. These companies usually release AI models, for which the training phase is arguably more important than the usage phase when it comes to ethics. It would be like if the manufacturer pre-calibrated the bazooka for a certain target. Sure, whoever uses it after may still use it in another, unethical way but the point is there is already a bias. It is important to consider ethical implications of the training materials used, especially when scraping the internet for material. Now, is a whole team needed? Maybe not, but you can't dismiss it that easily.
