I am all for regulator bashing (my favourite sport) but in this case it is a little harsh to say that 'pilots are forced into it by Regulatory Authorities'. In fact the Operator is to blame - they are ultimately responsible for running a safe operation.

There is also the non-compliance with FAR 135.207 as pointed out by JimL above.
