Normally I would find this sort of thing scary.
But, let's look at it through our un-biased glasses for a second.
A judge made a ruling that may lead to certain companies pursuing court orders to have the site blocked by telcos within Britain.
Now, this is not even the government censoring Britain's internet. These are companies who (obviously) have a vested interest in having the site blocked as the site exists almost solely for the purpose of illegally distributing copyrighted material (let's be completely honest here).
This is not the government trying to mute anyone's opinions.
This is not the government trying to censor what you are allowed to see.
I know people will probably claim "But it could be X, Y or Z". It is not. This is a judge making what is IMO a just and fair ruling that may or may not end up in private companies making an attempt to have a certain site, whose profits mostly come from distributing copyrighted material, blocked within Britain.
This is not as big as people are making it out to be and I'm not particularly scared (for now).
