Mentioned in the article: Spanish business using Facebook pages could be non compliant to this law. Same with others using wordpress, blogger, tumblr and so on since tracking cookies are been installed without a previous user acceptance. Also note that the business is liable for this, not the hosting service provider. I wonder how far hosting provider definition goes. If twitter is used in a company marketing strats, is it liable for the cookies installed by twitter? I don't see it different from the facebook pages cited example. The only practical option given this is to stop using those providers.
