Is there any biblical support for copyright law? There are people and organisations that state that copyright is wrong, and that copyright law should be deprecated. I think the same way but as a Christian I want to be sure that such thought is not be against the will of God.

Would being an advocate for the deprecation or abolition of copyright law run contrary to any Biblical or Christian principals? Is there any justification for copyright stated in Bible or other Christian sources?
It's a very good question, and not one which is easy to answer. But we are all called to make use of our talents, which I think may vary from gifts. Information is not necessarily subject to copyright - only literary / dramatic / musical works, films, broadcasts and sound recordings - basically, works where the author/creator has expended skill and effort to create it. And surely we as Christians should support those authors and musicians who clearly have a talent and a gift for their area to continue to write/create so that the greater Church benefits? 

As a Christian, personally I feel that copyright should not be abolished, though I do feel the term of protection is rather too long. I would be upset if Christians got into copyright court battles, as it is right if we want something to buy it through the correct and lawful channels, but not if we download it free from a torrent site or similar. There are of course flaws in copyright law - the exceptions, for example, should be wider and allow for non-profit institutions to do more with copyright works, but the general principle of others being remunerated for their work I think fits with the Christian faith insofar as it is not exploited.
