Accuracy ethics the incentive to build a good product and support it. Why bother investing in a new and better way of doing things if someone can copy you to the last icon and trick users into buying something cheaper. The one phone was sold as just like a iPhone to unsuspecting coustomers before ATT lost exclusivity.
Note many of the android fans hated the knock off just as much as Apple. The copied interface was not as polished as the standard Android is. Personally this seems a profound disservice to open source and android. They can stand on their own merit without stealing.
