Ok, so I just want to clarify here. I have no feeling one way or the other about this activity.
They are saying that there is no KNOWN benefit to this practice and there COULD BE bad consequences.
So how is that different than saying that there COULD BE benefits but there are no KNOWN bad consequences?
Aren't they really just reporting "We don't know one way or the other"? Except, as usual, the reporting has a slant injected into it.
