Well there are a lot of other means to share files
BitTorrent is by design the most secure & efficient today. However the problem lies on the share of the '.torrent' files, which is traditionally done by common websites, and thus be shut down.

What strikes me most when I consider the MegaUpload case and the fact that the Internet shall be a neutral place (ie, carrying content, that's all we ask to a network) is that the .com gTLD (generic Top Level Domain) falls under the US laws. By doing some research, I found that both .com and .net are managed by VeriSign, which is a US company and thus must follow US laws and allow to federals agencies direct access to their property on executive request.
The theory says TLD (Top Level Domains) do not belong to anyone. The real way is using allowing private companies to manage those TLD, thus allowing the country where they belong to gain the possibility of shutting down specific TLD or the whole of them. That is to say: a worldwide impact.
That is what happened to MegaUpload: the TLD
megaupload.com was seized by the FBI. However I don't know what happened to the servers. I only know they were physically hosted in Hong-Kong. Are the files intact? Has this government received & followed US government injonctions to delete the content?
To avoid the problem of proving that MegaUpload was not following the laws, which was expected to be very complicated, thanks to the SOPA & PIPA being postponed, the US government chose to use the joker card of the criminal organisation, the so-called 'Mafia' to shut the company down.
The game will probably be hard to play, since the technical advisor of MegaUpload already told the procedure was buggy...
The US government agencies will now need proofs.
Invoking the criminal organisation reason leads to think the US government wants a quick & simple procedure. Much more handy than the right path of the true accusation: allowing bad pirates to steal property from rich major intermediates (not authors).
The fact that they want to use shorcuts don't surprise me, since I don't have a specially huge trust in the US justice. But since I am no US citizen, I would righteously think I am safe from their misjudging and errors. The truth is I am not.
So the problems stays: the .com & .net TLD falls under US juridiction, letting their justice rule over their worldwide users.
What if you don't trust/wanna their national justice deciding what is right/wrong? You're screwed. Go away.
