The SOPA and PIPA (Protect IP Act) are almost the purest form of evil and corruption if you'd ask me.
Both are only designed because the (still) extremely wealthy music labels and film distributors (like Paramount) have so ridiculously much money that they can infinitely effectively lobby themselves into many people of influence in the USA. The USA is the instigator of this, though they did not design ACTA alone, but SOPA and PIPA are unique to USA.
Only in a country where you can sue McDonalds for dozens of $millions because the coffee you stupidly spilled over yourself was 5 degrees too hot, can you come up with such ridiculous extreme acts/laws and actually even manage to get it effective. "Only in America". Which is fine, normally, but not when this crazyness affects all of the world.
The mechanism why all the laws in the world, which are faithful to the privacy rights and don't facilitate censorship etc., will not work is simply because these old-fashioned overfed companies completely refuse to change their strategies and are desperately clamping to their old-fashioned albums/dvd's for high prices with tons of copyprotections and copyright-notifications.
Take a look at Valve. Their CEO said that piracy is a non-issue to their company. Why? Because they deliver services people nowadays want, he said.
They offer games for sale which you can download and install anywhere, anytime, on all your computers if you want and you'll never lose it since your purchases are stored online.
That's what people want these days and no DVD's which you BUY and then have to look through dozens of trailers, copyright-warnings, FBI-warning and what not.
Or a $2 MP3 with DRM which you can only listen on your PC and/or 1 mobile device.
I really loathe from these industries and especially the 'politicians' who pretend they serve the people, but actually are only trying to stuff themselves with money or the jobs they get handed over after doing the entertainment industry some favors. Blegh!
And I even haven't started about the consequences SOPA and PIPA will have....oh my!
