Yes, were TOM pushed or did they jump? Maybe Peel were courting TOM as we had been led to believe and then got wind that TOM were actually pulling out and decided to dress that up as a strategy ("Oh charter was never really the future and we can save money by not serving them...") or put it another way "I haven't been dumped, I dumped her first!".
I'm a bit baffled though as to where the savings are - you still need a terminal for AMS and ABZ, and the flights aren't that far apart that you can shut up shop for large parts of the day. And while there probably wasn't a load of money in two flights a week, symbolically it sends out the message that you aren't open for business.
Ah well, all will be revealed in the master plan...
