Just giving credit to the copyright owners
doesn't mean you are in
compliance with copyright law.
The question asked "ethical", not "legal". They are very different
for
a lot of people (and neither is a subset of the other, for many, such
as me - there are illegal things I consider ethical and legal things I
consider unethical.)
My point is that it is unethical to use someone's copyrighted material
without their permission or knowledge of exactly how it will be used. It
also happens to be illegal.
