I think that's the big one, and it's an issue ranging much much farther than WOTC and revenants.If I understand the question right, the people who 'blame' the internet are sort of right. Granted the internet has made it much easier to see all the people complaining about it (similar to how modern news makes the world look far more degenerate and ready to fall apart then it was in years past because now you get bad news from the world over rather just the highlights).
The real factor, I think, to the angst though is that because of the internet, and specifically places like this, make people realize that they're not getting the same cool toys because they're not a subscriber. That and most people have gotten used to the idea that PDFs on Wizard's site are free.
We as a culture, have gotten used to the idea that everything on the internet is free. And that's not just limited to the act of piracy. Take the New York Times for example, initially they put articles up on the internet for free (lets not get into a debate about logins) their reasoning for this was very very few people looked at the internet for news and most of them still bought a paper anyways, the internet was not cutting into their money. Now it is, but their having a hard time putting any kind of pay structure together that doesn't anger people.
We've all suckered ourselves into thinking that digital means free, and then we changed the world in such a way that print isn't profitable.
We're gonna have to convince ourselves that those little 1's and 0's cost money. I'm a subscriber, that doesn't mean I've completely convinced myself but I'm trying. I say bring on the exclusives, I like getting the stuff faster through DDI, but I love even more, not paying for it twice.
