To be fair, they're running this with oversight, the blog states they're ensuring the people employed are actually properly employed with the parent company. You know for sure that someone WILL run this experiment without those oversights, so while their "care" is probably more about liability there is still some truth to what they say.

If these guys succeed and this thing blows up, do you think they would not stop all this oversight and whatever “moral” boundaries they have now to make more money?

I do not.
