It most likely refers to Orange Juice The Brand (OJTB) and its dispute with Casetify over the passport/luggage-tag phone case designs. The public write-up says OJTB accused Casetify of copying its designs, while Casetify and designer Mathieu Desjardin denied it and said their work was independently created from airport luggage tags.

Why that reading fits

The phrase “not the orange juice?” looks like a reference to Orange Juice The Brand , not literal orange juice. In the reported dispute, OJTB’s co- founder Molly Jiang said Casetify copied their PASSPORT SERIES cases, while the other side argued the designs were based on common airport-tag inspiration and were submitted earlier.

What the reporting says

  • OJTB said it released its PASSPORT SERIES in June 2019 and later saw Casetify’s similar luggage-tag style cases.
  • Casetify said its partner Pangram Pangram submitted the designs on May 1, 2019, before OJTB’s launch.
  • The designer behind the collection said the luggage-tag look was inspired by original airport tags, not copied from OJTB.

Plain-English takeaway

So, if someone asked “Who is it copying, not the orange juice?”, the answer is: the accusation was aimed at Casetify, and the “orange juice” part points to Orange Juice The Brand.

TL;DR

A design-copying controversy is being discussed here, and the “orange juice” clue points to Orange Juice The Brand (OJTB) rather than fruit juice.
