sounds to me like files were taken down and then immediately re-uploaded by users. and potentially by users that previously downloaded the file. i mean were talking millions of uploads and downloads every day. add that to the lagtime of an infringement notice being sent out and responded to. it is totally reasonable to say that megaupload was doing what was necessary to prevent piracy. i never used their service, ive always fond it somewhat fishy. they are in it for the money just like their accusers and i really dont care one way or the other who wins.
sites like the pirate bay still seems to chug along nicely no matter how many law books get thrown at them. they are in it more for the openness of information and frankly i dont see how they are funding their organization, i certainly dont pay them anything to use their "service", while mega upload and sites like it want me to pay a subscription. i do want to see the mpaa and riaa both collapse in on themselves for failing to adapt to changing technology by crippling it so they can stick to their archaic buisness model. lets ignore the damages they do to the arts and society as a whole, let alone the damage they want to do to the internet. the fact that they want to reduce our tech level to what they would allow and to curb our our freedoms to share information just to further bloat their already bloated coffers is enough to make me want to see them burn.
best thing i can say is boycott their movies and music. there are plenty of independent films and music that are far superior to the drivel they churn out. we just need to show them that we no longer need them to enjoy media. on top of that film makers, actors, and recording artists, etc (the ones who actually make the content) need to do the same, and realize how much they are being exploited and having their creativity stomped out by these media corporations.
