Let us understand deeply about the term "Copyright".
The term copyright means,
a "statutory grant" that prevent others to copy the intellectual work own by someone
Protects from infringing
Can copy contents only after seeking permission from the owner, which is not possible in most of the cases
The drawback is that people can view the content and create their own content without doing "bit by bit" copying. For example, a software can be created by viewing another copyrighted software, by changing the look and feel, using their own coding styles and techniques.
