> These restrictions were enforced by the Stationers' Company, a guild of printers given the exclusive power to print—and the responsibility to censor—literary works.
> Prior to the statute's enactment in 1710, copying restrictions were authorized by the Licensing of the Press Act 1662. [Your quote about the Stationers' Company]. The censorship administered under the Licensing Act led to public protest; as the act had to be renewed at two-year intervals, authors and others sought to prevent its reauthorisation. In 1694, Parliament refused to renew the Licensing Act, ending the Stationers' monopoly and press restrictions. Over the next 10 years the Stationers repeatedly advocated bills to re-authorize the old licensing system, but Parliament declined to enact them. Faced with this failure, the Stationers decided to emphasise the benefits of licensing to authors rather than publishers, and the Stationers succeeded in getting Parliament to consider a new bill.
Which means that your quote is quite out-of-context. The Stationers' Company lost their monopoly over printing rights due to public outcry, and they failed to get a new law passed until they made a change to it that emphasised the protection of authors. That law was called the Statute of Anne.
Even earlier on, copyright "law" was used as a tool of censorship by the Queen of England (who was Mary at the time). Effectively, a publisher would ask the monarch for the exclusive right to publish a particular book, and a guild of printers (the Stationers' Company) was formed later that then enforced their own version of Copyright under these monopolies they were given.
The Statute of Anne was the first time copyright was actually a public law, that anyone could enforce -- and it was the first time that something you could call a "copyright system" was intended to protect _authors_.
Unfortunately the first part of the copyright bargain is implicit, not part of the law. With DRM, rightsholders get to have their cake -- our cake -- and eat it too. Not only is the protection granted by copyright now effectively perpetual, but they've purchased additional legislation such as the DMCA and endless copyright term extensions that punish people who are trying to claim their half of the bargain.
IMHO copyright should not apply to anything with DRM. Rightsholders should be forced to decide whether they want a temporary legal monopoly with no technical protection, or a permanent technical monopoly with no legal protection.
