Metaphors have the problem of being imprecise - I would say this is more like "are you using normal chef knife or your own special chef knife that nobody has?" or "are you using standard set of tools that every workshop has, or are you used to your own special stuff that nobody else has available"?

You're framing it as if the OP said "fuck fancy text editors or IDEs, I'm using notepad!" but I don't really see it that way.

As I see it, it's more like "do you really get that much gains from customizing your vim / Sublime Text / IDEA so much that you're incapable of working on someone else's machine? Is that worth it?"

Counter-counterargument:

All this assumes the difference in utility between a specialized and a generic software tool is as stark as your examples portray. That difference is quite subjective, and arguably lesser than your examples given how much effort goes into producing modern OSes and their ecosystems.

One size does not fit all. Also i don't need a full terraforming capable colonization kit where i am.
