How easy it is for you all to shout about over-cautiousness when, thanks to the regulations, there hasn't been a single incident. Well apart from D-CALM running away from some pretty bad stuff during one of it's flights...but that seems to get handily ignored here.
Perhaps those cocksure ladies and gentlemen amongst you, the armchair pilots and decision makers, would be rather more reluctant to scream for heads to roll if, heaven forfend, something came down in an unrestricted, ash-filled airspace, as a result of commercial pressure exerted on non-commercial organisations more interested in safety then profit.
To be honest, it's a little sickening how so many can claim to know so much about such a complex and oft-changing situation. We're clearly blessed with unparalleled levels of aviation expertise. Lucky us.
