Regarding Curd, some finished his type rating courses and P2F scheme via BMI, joined EZY and then got chopped. Some finished the BMI line training, thinking they would get an interview via parc for EZY to find EZY changed their requirements. Not a good feeling if you have training debts and paid for all of this.
I've heard from a few sources that some previous customers of curds have taken legal action against him. I am not aware of the outcome, but am led to believe it didn't reach court, which implies curd perhaps doesn't want it getting to court incase the claim is successful which would open the door for all the others in a similar position to bring successful claims. Certainly wouldn't want that debt.
The CAA cannot legislate against this kind of scheme, it needs to be introduced through changes in the law. There is nothing stopping anyone offering type training.
What does need to stop is the airlines accepting these schemes as a source of 'labour'. This is made more difficult when curd and the person liaising with him at ezy were best buddies since their school days.
