Indeed. Apple even screwed up on this with their

discovered this while researching the history of the logo while doing image
work on Wikipedia / Wikimedia Commons many years ago. It is still a

Despite its lack of COPYRIGHTability, it is a REGISTERED TRADEMARK,
which is more important to protect for THAT.
(Either protection would make a competitor putting it on their
products an infringement)
