Which line in the song didn't they like?

Haha, that was my first thought too. Australia is one of the world champions of the woke narrative. That could have been the entire text. I'm guessing Man-made virus, watch the millions die. Biggеst profit of their lives or the Gaza part.

Is this a euphemism?

I don't think so. In many hipster circles, hummus is a popular party snack. Maybe it's a hidden message and means 'You're my buddy' or something like that. :D

reminds me of the magic set

During the opening dance at the Inaugural Ball , I waited for the music to stop and Smooth Criminal to start. The outfit is reminiscent of Michael Jackson's. Only as a color reversal. :)
