😂🤣OP, I think you’re on to something

It's a callback to the very first movie when Luke drinks the same milk in one of his first times on screen.

Luke milks creature, takes a swig and stares at Rey, creature looks round at Rey plaintively, Rey looks concerned. :)

What to make of it? Luke makes do but that's his choice as a hermit, even though not necessarily the most comfortable. A hermit is a diametric opposite to a wealthy corporation - so who is milking whom or giving the finger? The lone fan may feel compelled to accept the product being offered by the corporates but he doesn't have to be happy about it - he has his own mental life unbound by them. But maybe the "milk" is the original trilogy which he/she may prefer, even though it's old and maybe a little boring since the fan knows the story all too well.
