I have no doubt that Kindle
users (and
users of other e-readers) «sign an
agreement,» but in the real world that means «check a box at the end of a massive and
confusing license or terms - of - service contract that no one ever reads, which has in any case been written to be both as reassuring and deceptive as possible.»
The licensing
agreements for stock photo websites can be
confusing, regulating how many computers an image can be stored on, how many
users can have access, and how many websites are allowed to display it.
