Lies, damn lies and statistics
The Pirate Bay is no longer blocked in Holland after a court found that blocking the site made no difference to piracy levels. If you pull the IFPI stats apart and find how they came about their results there will likely be many holes to their logic. The IFPI has to justify it's existence and keep donations coming in just like many of the other media lobby organisations.
Apply to the statistics the increasing availability of cheap legal alternatives, increased newsgroup signups, increased use of VPN's as well as flash based streaming sites and the numbers will likely show that the IFPI has their figures wrong as well as the amount they attribute to website blocking.
Although I have subscriptions for TV and Amazon Prime streaming, I pirate the same content I legally have access too. Artificial blocking of the services on rooted android devices as well as the lack of Linux support due to Silverlight DRM means it's too fiddly to use. Pipelight is an option but Sky only works with one version while Amazon another. Why go through all the hassle every time when you can click a few options in Sickbeard/Couchpotato and then fire up XBMC to watch the content in any room at a better quality than the alternatives.
