Minelab is no longer in charge of how Minelab operates. Here is a quote from the Minelab history page:
In 2008 Minelab became a member of the dynamic Codan Group of Companies. Our parent company, Codan Limited, is an international leader in high frequency radio markets with customers in over 150 countries. In 2009, Codan celebrated its commemorative year, marking 50 years of Codan communication equipment.
I've seen this too many times. A company gets bought out and the new company wants to wring every last dollar out of the company. I've been through this. How can we cut every possible corner to make more money. That includes cutting people or farming out work to less knowledgeable people. Ethics go out the window. "Just get it done. I don't care how you do it. Just do it!!! And if you can't do it, I'll find someone that can!!"
This is just a guess.
