Here's my take:
I'm not now nor will I ever be a fan of Anon, BUT I will admit they're in the right here, and all the folks hemming and hawing about it need to STFU.
Look, it DOESN'T MATTER if Megaupload was god damn pirate HQ, ok? The fact is that this is NOT about piracy, it never has been. SOPA and PIPA couldn't be more transparent if they were literally made of glass.
The RIAA, MPAA, ESA and their ilk don't give a damn about piracy because they know (like any sane person) it has virtually no impact: overblown numbers aside, piracy is for poor people who don't have or can't waste the money to buy a game or see a movie, and most music comes from YouTube and iTunes now so the music industry cares even less. All of these people give less than negative 800 shits about piracy. And even if they did, Megaupload is, at best, a street hustler, not a major cartel, to use drug dealer analogies.
No, this is about POWER. Its about establishing a single, resounding voice saying that these groups, these gangs IMO, control these industries and no one else. This is a powergrab pure and simple, and Megaupload was just the first victim. There is a reason that Google, who have NO reason to give a shit about us, came out against SOPA. I'll give you a hint, it has nothing to do with free speech. It's about power, or more precisely, about the RIAA, MPAA, ESA et al trying to take it all and leave nothing for the rest of us. Piracy is the excuse used to explain this cyber-lynching, and like most lynchings the supposed reason behind it is at best tenuous and at worst farcical.
I'm not going to defend Anon. I'm not here to say everything they do is right. But in this case, in this fight, Anon is on the side of the angels and we'd all do well to at the very least realize exactly what is at stake. It's not for Megaupload, or even Wikipedia or those websites that blackout yesterday...its us. Our power, what little we have, is being threatened and like it or not Anon is trying (and failing, by all accounts, but it's the thought that counts) to stop that. So in this situation, down in the trenches on the frontline of this bullshit war, either grab a machine gun and start firing or shut the hell up and get a deferment. I frankly don't care which anyone takes, they're both valid choices, but let's not start the friendly fire while we're under attack, ok?
We can all go back to despising Anon after this SOPA/PIPA thing is (god willing) killed, right now we need all hands on deck, no matter how grimy they may be. When the war's over we can sort out who gets a medal of honor and who gets a court martial.
