You are suggesting that Pinterest change the structure of its entire website to cater to Google's search algorithms. Doesn't make much sense to me. Why is it Pinterest's responsibility to change their whole website to cater to Google? Google could fix their search, instead. Pinterest offered to work with Google on this and Google refused.
So on what planet is Pinterest the bad guy, here? Because they didn't completely knee-cap their traffic because Google was too preoccupied to work with them on this issue? No. It's just a popular opinion to hate on Pinterest on HN and people like Google so the facts don't matter.
As far as the signup wall goes, well, that's on Google too. They could stop indexing sites that require registration at any point after clicking through. Goodbye Quora, goodbye Pinterest, goodbye New York Times.
