Why would anybody buy an icloud locked logicboard?

Iv noticed ebay is full of iphone 6 logicboard but when you look at the details most, if not all of them say they are icloud locked. Doesn't that make them completely worthless? The only purpose I can find is a person replacing it because they got a icloud locked phone anyway?

Some people know how to bypass the icloud lock. I was able to do it on an iphone 4 using a Russian software.
