hmmm, me it seems that you guys don't really have a solid information on how flight data monitoring happens in a modern airline. The data in question doesn't go on the desk of chief pilot, maintenance or even dispatch
There is a safety pilot office, where there is a team of qualified pilots who run those programs over the data. They only report to the management with names crossed out. Their target is not to blame someone, but to find tendancies in the fleets and thus increase safety. If one guy still diverts from all the others, then of course the name will be forwarded. But this happens in a transparent, written procedure, and only after several talks with the guys concerned.
I've been in several airlines where they introduced flight data monitoring, and lots of guys argued like you do, but in the end it all proved to be unfounded. If you treat the data this way. Of course I don't know how it is in your airline. Maybe not only the line pilots don't know how, but also yours managements...
