Ofcourse it would be copying, but so obviously and so blatantly is unlike Google. Btw, didn't understand your second question though.
Just our of sheer curiosity, why does Google+ have to copy Facebook in so many ways. I'm ofcourse talking about the 5,000 users (friends) in your circle limit which Google+ so blatantly copies. Why can't that number be 4,000 or 6,000 or 10,000 even?
