The stuff around SimCity in this article is poorly written. It seems the author has misunderstood it to have been a one-off special case. I looked back at Joel Spolsky's article, and he does make it quite clear that the SimCity example was just one of many: "it still ran old 16 bit software perfectly. Microsoft obsessed about this, spending a big chunk of change testing every old program they could find with Windows 95".

The article does later mention "Windows XP’s hidden database of app fixes" but doesn't appreciate that the concept really started with Windows 95, and in a big way, not "just to cover up one game’s bug".

Like the fiasco with Python3 and Wayland. It's so clear the developers just thought “Wow, people will just switch” not realizing how much people demand an absolute drop-in replacement and then maybe later you can think of slowly deprecating features to discourage new users from adopting them. Rust realizes this with editions. Yes, it's a big investment for them to continue to support it, but the alternative is that Python library maintainers now have to have this big investment themselves because they have to maintain like 6 different versions of the same library because Python doesn't understand the value of backwards compatibility. z/OS still supports 50s COBOL frameworks and for good reason. No one is going to rewrite that.

These developers when you talk about them really do not seem to understand that people aren't jumping to rewrite code or maintain different versions at the same time and very often even call them “lazy” for not doing it like they're not using their time for other things. Say you're a company, and you can pay a developer for his time:

1) Have him develop new features that make you more money.

2) Have him fix bugs that cost you money.

3) Have him rewrite existing code that will do nothing new, and will probably introduce new bugs again so you can later go to 2.

Which is more attractive?
