I suspect that Scubapro came to realize that the parts for life program was not as successful as they thought it was and the program was being abused by some of their shops. That is, I suspect that shops were claiming free part under the PFL program while they were charging customers for those parts. I suspect this realization occurred when scubapro started tracking their regulators by serial number which enabled them to see anomolies in service records.
No real data - just a hypothesis.
PFL has a cost and a benefit. Evidently, Scubapro felt that that benefits received from the program are not outweighed by the costs. Alternatively, a manager could have felt that part sales could contribute more to corporate profits than PFL.
