Indeed! It's a bit of an homage to one of the greatest video games of all time, applying it literally to our own bright orange cloud kit in a box ;-)

I thought it was on purpose, esp. with the main character of the main game is 'Freeman'

Given the use of that name and "Free Man" in the title, I suspect they're already aware of it and that it's an intentional reference.

Either by coincidence or by a very elaborate troll, the trash boxes in Berlin are also officially called "Orange Box":
