> I wonder who lobbied to have that date extended

According to the FDA, the manufacturers are doing ongoing stability testing, and as they find the tests are still effective after the date they initially estimated, they can contact the FDA to share their results and request that the FDA authorize a longer shelf life. This actually costs the manufacturer money since they'd be paid when people replaced the "expired" product they threw away, but they're doing it anyway because not everything is a weird conspiracy (and maybe also because the most shelf stable products have an advantage when it comes to what people order for their stockpiles)
