This means that the move back then to change the gun to a water pistol was an extremely bad move, no question here. But moving it back to the original meaning now is just as bad - it will just disrupt in the same way lots of newer texts that assume the glyph is a water pistol.
Doing the stuff differently compared to /the other group/ to know you belong to /this group/ is everybody’s favorite game.
Meanings change, jump from one word to another, words take the opposite meaning all the time. Pronunciations change too, letters that are supposed to sound differently suddenly don’t and other way around too.
Deliberately changing a language and pressuring other people to adopt certain changes in their vocabulary is something entirely different. That too has been tried often in history, but has usually led to conflict and was part of expressions of power.
Emojis can change their meaning organically too, if people just start using them in a different way. Eggplant emoji being the most obvious example I think.
But pushing an update to change the glyph would be about the most top-down and deliberate way to change its meaning that I can think of.
Chairman Mao enters the chat
It doesn't matter if it wasn't. It was done, and it was done at a time when there was political will for everyone to follow suit and be consistent.
The question is whether it's OK to turn it back. Because there ISN'T the same political will. And other emoji providers will NOT follow X in this.
Having X "go back" because the original change was "unjust" doesn't fix the underlying problem. It creates a new one.
Literally perfect application of the concept of "two wrongs don't make a right"
This is a problem since unicode characters are meant to be unchanging and rendered to the same glyph forever.
Stop destroying standards because they hurt your feelings.
