And the bizarre thing is...
That downloading copyrighted, or illegal if you will, software is perfectly legal in the Netherlands. You're only in violation with the law if you provide such material yourself. So isn't it a bit weird to block a source of "illegal" contents if the act to get those isn't illegal to begin with?
In my opinion this is a good example of what's been plaguing the Netherlands as of late; when it comes to the law the whole approach is shifting from actually taking action against the people who are in violation with that law right towards trying to prevent people in general from breaking the law in the first place.
Of course the problem with the latter is that this will also have consequences for a wide majority of others who simply comply with the law and now see that their daily lives are made even more troublesome. Worse yet: that is usually also the only result from such actions. Making it harder on the people to do something legal (out of fear someone might abuse it) while the people who were abusing such a thing in the first place simply continue on doing so.
You can see this on so many cases... Example? Well, it's illegal for a minor to have alcohol in his / her possession. Conveniently it's also illegal for someone to sell alcohol to a minor. As such the minor who buys himself some alcohol is hardly getting punished if he does, but the powers that be are all too happy to concentrate their wrath on the people who sold it to them.
The result should be obvious: it can be quite a hassle to buy yourself some beer. Some supermarkets here might even refuse to sell you (as an adult) alcoholic beverages if you happen to be in the presence of a minor (like one of your kids for example; you brought him along to carry your groceries and such). All out of fear; because the supermarket might be held legally responsible should the adult decide that the alcohol is actually for the minor.
So basically this whole Pirate Bay thing is in my opinion no different.
