It benefits everyone, if it is true. By your definition, there would never be a negative review of any product or service anywhere.
The other party has every opportunity to present the other side, if they wish. I agree that one should be very cautious about secondhand info or drawing assumptions, but firsthand experience is fair game. It's neither noble nor responsible to cover for anyone.
So, SB is the only source of justice in the world of diving? Kangaroo court adjourns, no defense is necessary, we'll notify the perpetrator after sentencing.
Sorry, but there are very few people I trust enough to use their word alone as a basis to destroy a business. None of those people exist solely as anonymous internet presence.
If there is a post here that references any active attempt to bring the DM into the discussion, I missed it. Are you implying that all DM's should monitor SB daily for slander and that in failing to do so they are deemed guilty of any allegations leveled at them?
I don't know the DM or the operation he works for. What I do know is that many of these DMs have been diving the same sites on a daily basis for longer than most people on this board have been diving. They know the sites and they know the profiles. Given the currents present on many of the sites, I'd wonder if the greater risk is an unaccompanied ascent, as opposed to ignoring the NDL of your computer and staying with the dive leader.
Dive computers have varying degrees of conservatism and most people diving them don't plan their dives. DM's actually plan their dives and while that plan may push beyond the conservatism of many computers, it is planned for safety. If you are diving a Cobra, you are not going to get the BT a less conservative computer would. Bump the conservatism setting up or leave the altitude setting at the more conservative of the three and it becomes even more conservative.
To me, it seems safer to stay with the DM and understand the profile you are diving instead of trusting a computer you may not fully understand. What are the options? Ideally, the group should stay together. I'll be pissed if I have to ascend with 1400psi because your computer tells you are in deco.
So, do you ascend when your computer tells you and leave the group? This is one way many incidents begin. I wouldn't recommend it.
I doubt that the profiles chosen by the DM are typically to blame for divers getting bent. I tend to believe that the cause is likely poor ascent skills possibly combined with a sawtooth profile resulting from poor buoyancy skills. Ops don't stay in business by bending their customers.
As for the O2, they should be honest. As Catherine said, many places don't require it. If that makes you uncomfortable, don't dive.
