Tank holders on boats are prime suspects for this sort of problem. I've seen it happen several times; insert the tank in the holder, wing gets pinched between the backplate and the tank holder. Then you have not only the weight of the backplate, but also the tank and reg involved.
I'm not saying this is what happened here, but it does happen a lot, often right around the OPV. If I were in DSS's position, and the tear indicated it....I do know from experience that dive-rite, another company with a good reputation for customer service, charged a colleague for a replacement bladder when she sent them a wing with a pinch flat.
OTOH, there are some companies in certain industries, (like mountaineering equipment or tools) where the perception of reliability is paramount to sales, that will simply replace any gear for any reason, simply for the bragging rights. Of course, this is a lot tougher on a small "boutique" company than on a large more diversified company. I'm pretty sure Marmot (or some mountaineering brand) replaced a guy's sleeping bag because a bear ruined it....and then bragged about it on their website. Tough to buy that kind of advertising.
