Ah, so the comment was directed at me.
Look, you can talk about company "morality" but Panasonic's responsibility is long over for most any of these parts; it's likely they were dumped en masse
and the seller on eBay bought them knowing what they are and is recouping costs. Large companies like Panasonic don't make a lot of repair parts and don't keep them just sitting on the shelf for 5+ years as there are costs associated with that that need to be amortized (or, something else
could be taking up that warehouse space.)
If the seller on eBay finds they are selling, prices may go up both to reflect the market for the item and to make up for losses on other electronics parts purchased that have no takers; that's the way business works.
My comments were not meant to be gut reaction oppositional but rather to reflect how a market economy should
By the same token, if the new price is too high, the eBay seller could be sitting on a pile of otherwise useless lasers, so there's incentive there to price them fairly.
