I think he knows exactly what hoarding means.
Just go back to January 2011 and count the number of ebay auctions that appeared (and continue to appear sporadically) for lots of Kodachrome slide film. Clearly a number of people bought 'extra' and either weren't actively shooting or weren't engaged enough to keep track of the ability to get the film processed. The processing cutoff was not exactly a secret for at least 2 years prior to 12/31/10. And to think of all the lovely rolls of K25 I could have shot in 2010 if not for these idiots.
Every hoarder sincerely believes they need and will use the things they hoard.
About B&H it should be pointed out that sometime in the last year or so they changed their decades-old business model for film sales. They were a high-volume, low margin seller of film. Now they are a high-margin film seller. Translation: B&H is no longer the go-to for best price on film. Whether or not that translates to lower volume, I believe it will take a while for buyers to adjust to the change. In fact I think they're banking on it right now. But there are already a few better options out there and I believe we will see more appear as time goes on.
But, the base price increases on film are outpacing inflation, one cannot deny it. It seems to be a perfect storm at the moment. Covid+politcal upheaval+high inflation all combined with hugely increased demand on an aging manufacturing infrastructure that was just barely hanging on. Even if Kodak, Fuji, et al, could have seen it coming 5 years ago, I don't think they would have believed it. The only consolation we can take is those extra $ are going to maintain and upgrade that manufacturing infrastructure. And to pay employees a living wage. I'm pretty certain for Kodak that's true. I don't know about Fuji🙁
