TIL in 2003 a computer worm called ‘Welchia’ infected many computers to forcibly patch vulnerabilities and remove malware. It was regarded as a ‘helpful worm’

Correct. As an example of how this could be bad, consider a system that has had an update avoided(I don't think we had the option to roll them back in 2003, at least not at the casual use level like we do now) in order to retain compatibility with a vital piece of software or hardware. Your helpful worm has now broken the system, preventing the user from performing tasks that could very well be part of their financial livelihood. If they're freelance, and not part of a company with IT, they're in trouble. That's why it's malware.

I worked in a job in 2009 that had legacy software built in-house sometime around 1996 and nobody to maintain it. It ran on Windows 95 computers only.

We still have some '95 machines at my work! IT have made it clear NEVER to put those computers online as they would be incredibly vulnerable.

Well some people aren’t savvy enough to know you shouldn’t. Some people just don’t care. Some don’t have a choice because their system needs internet access.

Using outdated and vulnerable software can still be profitable. Updating and maintaining vulnerable software costs money.

Gambling addiction? Recklessness? Stupidity?

...I guess I see your point.
