No.
Intellectual "property" has no moral grounds for protection. Society benefits whenever one persons work is used, for free, by many. Anything that I can use with no net cost to society (ie: no cost to me and no loss to anyone else) is an advancement. Your energy has already been spent; If I was to waste my time repeating your efforts, the effect is a net loss to society because my time could have been more productively spent. This is generally accepted as fact.
Intellectual "property" legislation is about creating incentives. It protects your work so that you have an incentive to create it in the first place. It is an entirely artificial system, with no moral or altruistic basis. As such, it is open to debate. How much incentive is needed? What form should it take? Who decides on value? But most importantly, society must still come out ahead. So, having said that, in my opinion, it's just a matter of talking price, and as far as I'm concerned, intellectual "property" is overpriced. The net effect on society is negative, because current laws stifle innovation and impose unnecessary and unfair costs on later inventions.
So it's a protest. We don't like the legislation as it stands - Brands and trademarks are used solely for corporate gain, with no benefit to the consumer; Copyright is excessively long and stifles fair use and advancement of the arts it purports to protect; Patents are trolled for all they're worth, ignoring the principles of prior art and novelty, resulting in a net loss to society. We pirate because we don't buy politicians in order to alter the law for our benefit, like corporations do, our actions draw attention to the gross inequity of the current situation, and force changes.
So don't even try to tell me I'm acting immorally. If legislation was fairly drafted, piracy wouldn't even be a blip. Not even a tiny speck. And society would be better off for it.
