My father has been working on his accounting software (he's an accountant mainly) since Delphi 1. He might be the only single user paying for the enterprise version. Or maybe there are dozens of them.
Whenever I speak to him, he raves about whatever the new version of Delphi is.
I briefly worked at a Delphi place (zero guesses why I didn't stay), and it was similar there, people being enthusiastic about in my view quite minor releases. One guy had a personal website complete with hand written HTML2 and a collection of Delphi freeware utilities. It was not a bad trip down memory lane, but everythig about the place screamed 'dead end' at me.
That is the large majority of shops whose main business is not to sell software, rather something else.
People rave about what they know, aren't aware HN exists, leave at 5pm, enjoy weekends with family and friends instead of uploading stuff into GitHub, and are happy.
