Polaris swag and labeling != Polaris hard product.
Polaris swag and labeling = Polaris soft product.
Your type of seat indicates Polaris hard product and searching the seat maps for the EWR-ZRH flight, I don't see Polaris hard product seats (unless the seat map is wrong). Therefore, I conclude you didn't fly on true Polaris.
As I said before, it's not the norm, there's a whole thread of typical compensation values showing you that not providing miles/$$$ for broken anything is not the norm.
Nowhere did I say you 'needed' the miles of ETC. I merely suggested if you want it, to reply back to your customer email and ask for it. All corporations have auto-responses generated. There's simply not enough time in the world to give personalized responses to every single email that traverses United.
You ended your post with "There was a reason why I stopped taking UA and now I recall what it is...". And the topic of your post is "broken entertainment unit = no compensation?". So I don't think it's too much of a wild-card for me to assume that these are related.
