Well under the surface there is alot of subtle control going on especially with the internet. Its not all freedom in Thailand. The King is another matter, they take the slights against the King seriously and tend to pick out people to make an example of every now and then.
I remember being in Thailand when someone did a piece on the King on youtube they thought was mocking and shut down access to youtube. My friends were sending me stuff to look at here and there during that year and i couldnt access it. They lifted the block after a time.
I dont know where they are going with the case linked here but I guess we will have to see what the agenda of that is and what lies beneath it.
