Absolutely agree 100%. ^
At LGW we've been told by the US Immigration people we work with there that if passengers haven't completed ESTA they will not be allowed to travel and if they do get through then the airlines will be heavily fined. Obviously BA are not prepared to pay fines for those who don't want to do it.
So it takes a few minutes of your time. Which is easier, a few minutes of your time or a lengthy interrogation at your US entry point, perhaps followed by you being refused admission and sent straight back? I would have thought the answer is obvious.
