Music file-sharing falls by 50%

[zombywoof]

Peer-to-peer file-sharing activity has dropped by half in Europe, following the legal proceedings brought against Napster.
Latest reports from Jupiter MMXI indicate that since the Napster boom in February, the reach of file-sharing sites across the European audience has fallen from 16% to just 7.6%.

Just wondering. For those of you who live in Europe, is this really the case. Has legal issues made p2p file sharing more difficult and is perhaps being driven back underground, or is it that there are so many p2p apps out there that the sharing community is just spread out using different networks, or has the phenomenon of filesharing waned a bit since it is so common these days?
