It's one thing to have concepts, ideas, and patents. Every one can come up with them. To actually have the abilities to implement and resolve enough technical issues to make them a reality, like Samsung do, is something to be commended. Now that companies like Samsung have made this tech mature enough, other companies, Apple included, have shown interest. There will always be people who try to advance technologies, and there will always people who only show up to make money on these technologies.
