As someone with a mild enthusiasm for linguistics and phonetics, I like it. My only complaint is not using eth too. I can’t imagine the inconvenience is much different than emojis or emoticons. But in any case it seems more like a gimmick than an cry for attention, certainly not as much as a whole picture (invisible to screen readers I imagine) targeted at them in retaliation. I don’t get the hate, and the “This person just wants attention!” Seems way more performative and attention seeking.
