Did Oracle infringe Amazon's copyright here? Ars Technica contacted Oracle to ask them if they had a license to copy Amazon's S3 API. An Oracle spokeswoman said that the S3 API was licensed under an Apache 2.0 license. She pointed us to the Amazon SDK for Java, which does indeed come with an Apache 2.0 license.
I only brought up the Apache licence, because the article we are talking about, brings up the Apache licence.
