@HarryT: At least in the USA, additions made to the set of installed software is not "modification" of the original "Amazon Software".

Also, Linux (*nix in general) is controlled and configured by plain text files (unlike the use of binary files by some systems), and those files are "data" not "software".
In the USA, different rules apply to "the associated data" that are not covered in the agreement.

Still, the **intent** of the Amazon agreement is clear, even though the lawyer who wrote it left some pretty big "holes" in its language.

Somewhere in that agreement there is probably a catch-all phrase about "mis-use" - which is defined as anything you can get a judge or court to agree on.
