I wrote to BALPA abut this subject in 2002, then spoke to Chris Darke personally about it. Sadly, my concerns were not taken seriously, as were my warnings on PPRuNe that if a stand were not taken then, this practice would be the norm and ingrained in the aviation industry. The IPA magazine actually ran an article asking for members to recommend the best P2F suppliers.
Pilots only have themselves to blame for this situation.
