You're right that the terminology has been tricky to contend with, although it's hard to say what a 'least-confusing' name would be. Other names for the phenomenon include "Pi spin glass" and "Floquet time crystal," neither of which seem to definitely avoid any confusion. The accounts of these phenomena are becoming more clear over time, which will help, but given the name and the images often used in the press, I understand why it can come across as fantastical.

"Chrystal with periodically re-arranged structure"?
