Where did I mention "death" or anything related to what you claim I said in my post you reference please? And what claims are you objecting too? Are you objecting to the fact that these companies are indeed tiny/diminutive when compared to AL, SP, Huish Group for example?
Good for you but you live in a privileged and prosperous society/country in very big contrast to many in the rest of the world, such as where the OP lives. We can barely afford one regulator let alone the so many you appear to have and hence we need to protect our investment by buying from a well established company with worldwide service and representation especially a company such as SP that has all of these in addition having some of the best products, regulators in this case, in the world with prove track record in reliability, performance, stability, service, availability of parts and service in addition to competitive prices at the different price points. My opinion is shaped by the opinion and requests of my clients/students who insist on buying (after saving for it for a long time) a brand name regulator, mainly SP, and forego other options from lesser known brands with lower prices just for the points I made above. These third world people have a lot of common sense and savvy to make up for the lack of the financial resources and luxuries you have in your happy land.
If you believe this part of the Ark story, then you have to believe the entire story and know that these "amateurs" had an incredible most powerful, all knowing, all mighty, all great and omnipresent force behind them, God himself!!! The "professionals" who built the Titanic didn't have the big Guy himself guiding them.
There are millions of divers making 10's of millions of dives per year and yet no one is dying because of bad technicians doing bad things to the regulators, you have already insisted that there are/were no deaths due to equipment problems, and hence your argument holds no water and isn't a universal problem or stands to be a real problem at all. The absolute majority of people have a certified/trained technician do the service and not themselves and yet no recorded deaths anywhere, again according to you.
P.S. I changed the terms "miniature, make-belief" in my post to "tiny/diminutive" after a very polite and professional request from a friend on SB. He made his point with utmost respect and I changed them. I made the change mainly to avoid creating a controversy detracting from the main points in my glorious reply
