You seem to not understand the difference between lifetime defect warranty and lifetime wear warranty.You've failed to state your case. I'm well aware of how a ponzi scheme works too. You pay out more money to investors than what you take in. Try understanding what it really is so you know the distinction between a ponzi scheme what could just be a bad business decision. They've been doing the lifetime warranty for over 6 years at this point.
Also keep in mind that many parts already come with a lifetime warranty. Rockauto also sells lots of parts with lifetime warranties and I've also taken them up on their coverage before too. Certain lines like Moog, Monroe always had lifetime warranties.
30 years ago I bought set of screwdrivers at Sears. The most used one got replaced about 12 times in those years. But Sears never gave wear warranty and would you bring wear screwdriver - they would not replace it. I just "made the screwdriver fail" when it start showing wear. At the end, -Sears is out of business.
Lifetime replacement for wear out parts is Ponzi scheme.
