Or maybe they're right. Not too long ago many messengers and social networks all had their own set of emojis. Some supported even custom ones.

The convergence on Unicode is very recent.

It makes me rather excited! Maybe there are some easy "memory illusion" tricks waiting out there somewhere to be discovered. (I am strongly pessimistic regarding the future of humanity overall, and I think we are all doomed (me, and everyone else). So I think someone playing a memory illusion in a radio would be rather neat, a new fact about us humans, and not something that I'm scared of.)

If you are not familiar with Unicode standards, it would be quite reasonable to assume we "used to" have an emoji and it disappeared.

Like the Mandela effect.

I meant more the denying reality aspect of the subreddit. There are some users there that go straight up into "someone must have altered the timeline" territory because they insist they are right.
