I was merely intending to mean, that an operation like EZY with several close destinations, that this is an ideal solution to tech problems.
ATC have no right to ask why the diversion, if you have already said 'commercial reasons'. They get far too nosey about things that arent their business. The airlines are their customer - NOT the other way around!
If it were tech reasons, I am sure almost all crew would admit it, to seek as much assistance as possible...
