There's nothing wrong with copying
I'd love to get back to a world (if it ever existed) where a company could protect clever technical discoveries with patents, but where no-one owns ideas of shapes or sizes or colours. If one company releases a triangular smartphone and it sells like hotcakes, then great, everyone should build them.
I don't want to live in a world where companies aren't allowed to build things their customers want, just because someone else has already built something similar.
