I think the point being made is that there are water carriers on the pitch, shirley?We criticise the ref for his decision making, not Biggar for taking advantage of it
In response others are criticising Farrell for taking advantage of a similar bit of poor decision making by the ref.
That is the difference between the 2. Taking advantage of an unfair situation when it is to your benefit doesn't make you a hypocrite for then complaining it is wrong when the reverse happens. When have you ever seen a player protest a wrong decision that was in their favour? They don't they keep quiet. Does that make them all hypocrites when they protest when it goes against them?
