I agree - when it comes to web design, people steal ideas from everywhere. The way I see this as a bit different, is that they actually took the design verbatim and then cross linked the assets...so technically, they stole the bandwidth and images which may have royalty's associated with them.
As for duplicating the layout and taking the concepts, that's fair game in my opinion. The actual graphics should not be stolen and re-used.
They ripped off the concept and idea of the pricing table, yet they didn't flat out take the design and just modify the text. These guys took every single element, changed no style.
