Using emojis as bullet points has been a thing in tech articles since emojis were a thing, so if anything, ChatGPT loves using them like that because people love using them like that. (I.e., it's not a good litmus test for AI.)
I somehow remember ChatGPT not using many emojis until the past few months, and all of a sudden it uses tons. Seems like they tweaked the system prompt.
