P2P file sharing and Australia banks invested at $2 billion; illegal??

According to the data available from Whirlpool, 57.7% of Australians share files using P2P.
A few weeks ago, I wrote about the possibility of the content industry owning shares in the broadband networks and that if they did - then P2P was merely another distribution channel.
Today, I’ll revisit the scenario, but this time from the perspective of policy makers.
Consider, if you will, the role of the Australian government in P2P file sharing.
The Australian government originally owned the majority of Telstra’s shares and has been selling off chunks since 1997.
Telstra claims they have 5,507,000 subscribers of Australia’s 7,228,000 internet users.Therefore it follows that Telstra is the Carriage Service Provider (CSP) that enables the highest level of P2P file sharing.
