In a similar vein, I literally had a shirt up on amazon called "shrug emoji" that was just a `¯\_(ツ)_/¯` on a plain shirt, and it was taken down recently (after being up since 2017 without issue), because apparently a company owns the trademark to the word "emoji" now.

(Unfortunately amazon merch's contestation process requires you to submit documentation that you have license for the offending trademark, with no ability to claim misidentification or nonapplicability)
