I do find all this finger pointing at the helipad operator a bit out of proportion. At the end of the day it is a pilot's responsibility to make his own assessment of a whole range of characteristics about heli landing sites, some prepared, many not. These of course should include looking at area, slope, obstacles, approach/departure routes and any features (like upwind buildings)that may affect the local wind.
In this case it was a daylight operation and enough info about the wind should surely have been known from both the local met and from just assessing it on the ground before departure. Like we all do from private sites, regardless of windsocks. It was obviously very strong but you've just got to fly very cautiously, with enough power reserve - and an escape route.
A more obvious risk, looking at the site, would seem that with a location that requires approach/departure preferably over water but otherwise buildings, either a single with floats (unlike this R44) or a Cat A operated twin would provide much greater safety.
