They are dead serious about supporting legacy stuff, and it long predates the advent of PR. They've been doing it for 100 years, and it's part of their DNA.
If you go to one of their service centers (there's a lot fewer of them, nowadays), in the back, you will often find camera bodies and parts for cameras that are fifty years old. They won't necessarily fix it under warranty, but they'll definitely try to fix it, if possible.
When 9/11 happened, they had cameras in the Melville service center from The Pile, covered with that dust, and they busted their butts to get them fixed up and back out there.
They are a very old company, and take their work seriously. There's lots of things to complain about, with them, but they are serious about Legacy.
