Are you seriously going to tell me you can't see the similarity between:
http://www.infinum.co/services http://kintek.com.au/services/
That most websites don't have that curve, or the spacing on the left/right or the little bar above the menu rather than below or any of the things that screams a rip? Then scroll down to the footer and they're identical.
Go open any other software consultancy website and see if you can see those same similarities?
There's so much more to a design than just the grid layout.
I've seen this happen myself at a company I consulted for, they told the designer they wanted a website that looked like X's website, so the designer pretty much cloned the website, moved a couple of things around and changed the logo. Client thought it was wonderful.
On a separate note, does anyone else find the indenting of the HTML on the infinum site to be very odd?
