I guess I should feel relieved that I don't at least have my work discussions littered with these ones. But they're not too different from the set of infantilizing pictograms that did make their way into the standard & that grown-ups are now expected to deal with.
Really? We use slack and all staff has access to add new emojis. You can just imagine how that would turn out...
I didn't have a huge beef with the proprietary emojis on old skool Skype and MSN, TBH - they were technically bound to those platforms, and the platforms mostly to private social spheres where they'd form part of the local slang. (And where Skype was used at work in the 00's, people actually refrained from them and acted in a businesslike manner).
Modern day emojis being part of unicode implies that they're somehow universally understood, and that it's fine to sprinkle them around in any kind of social context. Quite horrifying, really.
