Pirate Bay is not doing anything illegal, it's the people who are illegally downloading games without license who are the real criminals. Saying you should prosecute people for providing a frankly wonderful infrastructure (torrents can be used for legal reason too and torrenting is one of the greatest forms of file-sharing) that a certain number of people use for illegal reasons is like saying you should prosecute the people who build roads because people use roads for illegal reasons (smuggling, car chases, speeding etc.), which is frankly appalling.
There are ways for developers and musicians to deliver products that are near impossible to pirate. Look at Steam: one of the greatest success stories. No DRM, no secret software that spies on your computer, no malware, no bullshit, and frankly, it works.
The best thing, and quite a likely outcome, that pirating will bring about is the destruction of the corrupt music producers and games publishers who exploit decent musicians and developers. If they collapse, then music and games will be cheaper, because its the producers and publishers who take the largest cut from the profits in the first place.
And even if you disagree with pirating, then fine, but this trial was an entire sham. It was brought about by a collection of businessmen not interested in protecting music, games or any other form of art or entertainment but making money who are entirely clueless about how the internet works, much like the court, so they just screamed 'INTERNET EVIL PIRATES BLAH BLAH BLAH' for a week. It stops being about piracy any more and sets a dangerous new precedent: Big businesses being allowed to legislate from the courts. Never mind the stranglehold big business has over government in the first place in the form of lobbying and paying off politicians and committees, being able to win court cases by presenting lies, mis-truths and misleading the court on all counts by going after people who possibly have not enough money to hire any sort of decent defence against their own legal teams and they are effectively allowed to set legal precedents.
A few years ago, Norway set a fantastic legal precedence: the film industry brought a case against some guy who had been ripping his DVDs onto his PC for storage reasons. The court ruled in favour of the guy, saying that because the DVD was his physical property, he could do whatever he wanted with it. If we see that kind of progression in other countries, we could finally get rid of stuff such as those horrible EULAs and SecuROM.
