I've had nearly every brand of folding knife I've owned come open in my pocket. I can't think of any I've owned that has not opened at one point or another while carrying except Chris Reeve and Case... Kershaws with the speedy unsafe feature were the absolute worst and I will not own one. Benchmades with Nitrous or their old assist, and yes, even Spyders. My old SnG's bit me more than once reaching in for keys or whatever... I've cut my hands plenty of times on Emersons, too.
I play with knives. I get cut.
I spend my knife money with the companies that I choose based on many factors, service being as important as the knife.
I really think that there is a lot of conjecture and jumping to conclusions here, if not personal bashing of the owner of the Company in a forum that he pays for, around one person's gripe. I know, big company, thick skin, free speech, yadda yadda, but frankly, if someone wrote of me like some of this in my own forum, well, let's just say that Ernie is a better man than I, but I know that already. I'm not here to validate or challenge the gripe.
I've only ever returned one knife to the factory because of poor quality, a Caly3. The one I got as a replacement was as poor if not worse than the original and I haven't bought another Spyderco since, but I don't go over to their forum and whine about it, either. It's not my style. I vote with my wallet.
I have not found a Knife Company with more heart or integrity than Emerson, and I carry their knives daily. I'm not a highspeed or hardcore bada$$ and will never purport to be, but in the office, in the woods, in the dark... I carry an Emerson, because the have met every need I've asked them to, as a knife and as a company.
