How do you know that's the case though?
Exactly. Things may take a completely different meaning depending on the people you're with.
I remember a conversation from a while ago when young me called a gf of mine the "prettiest black girl ever."
When she asked me, "why not just prettiest girl ever?" I was completely dumbfounded because while that's what I had meant, I realized that I no idea what a simple qualifier could do to the meaning of the phrase for someone.
I learned a valuable lesson that day that I won't ever forget. I don't considered myself 'censored' since then, just significantly more tactful in social situations.
So perhaps like ribbing people in a tongue-in-cheek fashion for using the "wrong" text editor?
I think that sort of thing is fine and generally accepted, provided you don't become hurtful or vicious with it.
I find that people give you plenty of opportunities to poke fun at them without being lazy about it.
edit: The general idea is to only make fun of things people are completely secure and confident about, otherwise you're not being funny, you're being mean.
