I’m going to throw my hat in the ring on guesses.

Somebody was debugging a hard to find problem in the Amazon video client. In an attempt to try to figure out what was causing it they had it print out a message using the subtitle system. They had been looking at it for many hours, not able to correlate a certain piece of media that trigger the error so the humorous chose I hate you as the flight to let them know it just happened.

And somehow that piece of Dev code made it to production.

I wouldn’t worry unless it tells you to feed it a cat.
