Sometimes most people with the knowledge are gone, the people left need to keep things relatively up to date for security reasons, but the legacy systems aren’t as nice, so it takes time and is generally unfun to do. Sometimes a new law in Europe goes live and you should be able to add a pop-up somewhere, but when you follow the docs on how to update stuff, it doesn’t even work for a myriad of reasons. It’s not like maintaining a software for 12 years really, which a ton of businesses do successfully. When you’re just keeping something alive that works and almost never crashes, you get to a point where doing mandated new updates gets harder and harder. And now with the shops gone, there’s even less of a money incentive to keep the thing going :(
