It is also true about the locking of the ECU. Personally, I don't care that much on this and it is a way to protect the intellectual property of the tuner. The factory ECU is supposed to be locked too and the majority of owners never care about it or never have a need to unlock it. If someone modifies his car heavily and constantly for many years, then yes it is another story and it might not be optimal to rely on a single tuner. However, such people are kinda sick and in many cases they won't even care to start a tune from scratch with another programmer. Sometimes even intentionally.

The problem with locking ecu occurs when people sell their cars. a lot are not heavily modified just tune and header/intake.
Often they remove header/intake but leave tune in ecu, as it was done by tuner and they never had cable, or they sold cable or lost it. but end result is new owner gets car with tune in it, that sometimes doesn't run to well as other mods removed like intake/header.
they then take it to dealer or another tuner to look at and ecu is locked to brzedit or ecutek or hks flash editor. any you require a bunch of different expensive software to remove old tune as all the lock systems are different.
theirs even a guy that wrote his own coding and apparently if you try to read the ecu it actually erases ecu tune instead, this apparently includes doing a simple Query ECU in ecutek.
in some cases its easier for people to bin the ecu and put in spare ecu rarther than buy expensive tune software/cables.
It would be heaps better if the tune systems that locked just READ locked ecu, but still allowed you to write over it to return to stock.
