I concur. We (as a society) have tolerated far too many frivolous lawsuits that are contaminating our moral compass and doing nothing more than fueling one's greed. Everyone involved, directly or indirectly, in one of these circus events contributes to their proliferation. It may be summed up best by Don Henley's song "Dirty Laundry."
Yes... you can try to contact other divers. But if this particular unnamed shop has recently stopped "pumping nitrox" as you say, then why don't you consider that a step in the right direction instead of dragging any I-want-to-get-rich schmuck in on your immoral delusion? The diving industry as a whole has enough troubles without the likes of you tainting its reputation by blatantly (and publicly) proclaiming a fault and demanding retribution for an act that is most likely an honest mistake.
You would probably do good to dispense with the thought that it was intentional, but given our nature, arrogance will trump all logical arguments. My logical argument is as follows: If it is true that nitrox is no longer being dispensed at this shop, it would seem that the person in question was either informed of or discovered said problem, and subsequently ceased using the defective equipment to protect the diving community. And if said shop/person is morally conscious, I suspect that your concerns would be addressed and satisfied to the best of their ability, without the need for public litigation.
I feel compelled to offer one of my favorite aphorisms... "Friends come and go, but enemies accumulate."
