I pirated everything in 3e because I didn't have any disposable income.
Then I'm sorry, that's just despicable. You don't have a "right" to free entertainment, unless it doesn't cost anything. If you want to watch TV over the air, fine, if you want to pirate cable, it's wrong. If you don't have money for D&D, go without or use a free alternative (like the free games out there), don't steal it. (And don't even try to tell me it's "not stealing".)
I think it's likely that companies that piss people off will at least receive less legitimate business, while their piracy will not decline. As a result the percentage of people pirating their product will rise. Either way, I like how Wizards has not made a big deal about pirating things. It's ultimately futile to do so. If they did, I'd probably go back to pirating their stuff, honestly.
Pirating to "stick it to the Man" is not a ethical attitude. Saying you're going to pirate because you don't like a companies policies is crossing the line. Do without!
To be honest, whenever I see "piracy is inevitable" argument, I come back with "counterfeiting is inevitable, but that doesn't mean we don't try to stop it". So, I think we're going to see many changes over the years, including the following.
* ISPs are starting to cap "unlimited bandwidth", so I see it going to get harder to mass pirate items. All the ISPs will soon do this--in the past electricity was offered at flat rates but they had to change it. Competition won't be enough to stop this change in economic policy.
* ISPs will soon have to become gatekeepers--in other words, they will start to share responsibility towards this type of activity. Some Supreme Court justices have hinted they will make this type of decision soon. You'll find yourself cut off from the Internet if you engage in this activity.
* Saying Piracy won't impact the bottom line is ridiculous. If more people think it's okay, and punishment isn't enforced, it will have an impact.
* It's getting harder to be anonymous on the Internet. You can pretty much track a person to geolocation and I think ISPs are coming up with new ways to make things traceable. It's going to be very hard to keep yourself anonymous.
* DRM is only irritating to people because of how it works. People will use DRMed software if the software is not that intrusive and/or the benefits outweigh the costs. Team Fortress 2 is one of the most popular games despite DRM, also iTunes.
* I can see the Courts and Congress deciding to treat piracy like traffic tickets--download a book or CD, pay 5-10 times the amount of the retail costs, no million dollar fines applied. If they keep the fees down but treat them like traffic tickets--making them hard to challenge and the penalty low but applied like tickets, soon, people will stop pirating simply because they can't afford it. The laws have to make it so people fear piracy. Illegal Drugs are a problem but most people won't take them because of the laws against them. They are going to have to start jailing people to make people fear the law.
* I think they are going to work to educate people the problems with warez, etc. There are certain forces (such as Richard Stallman, etc.) that want people to not feel guilty about sharing files ("information wants to be free", "piracy is not theft", "it's like buggy whips", etc. It's important for people to educate about the downsides and fallacies of these arguments. There are reason creative people get royalties, for instance, it's a fallacious argument saying "why don't bakers/bankers/construction workers get royalties".
* The biggest issues I see regarding piracy and reduced royalties as "not relevant" that people are ignorant of is that Big Business is using this to get ahead. While people like to think of organizations like ASCAP, the RIAA and media companies as "the Man", the people who benefit most from loser rights are the media companies. Google would love to have the Orphan Works bill pass, or for there to be no royalties asked from YouTube. All I see people doing here is passing one big conglomerate over for another, and reducing the economic rights people worked hard for years to build.
