EDIT: Apparently it's a legit trademark (I searched for it and it's active). Here's a recent post about it from Ryan Dahl: https://tinyclouds.org/trademark
Also as someone pointed out on Twitter it's probably not even in the right category to protect against the use in educational material. Also even if it were it's probably nominative fair use anyways.
Disclaimer: I hate Oracle
Yes, the precedent that they actively defend their trademark.
If they don’t and someone challenges it they will most likely lose it and then it’s out with the Kleenex.
They'll defend it to avoid genericide.
