Re:
VooDoo themselves aren't making anything, and haven't since 2011/12 - hopefully just dormant, but possibly dead. They took the VooDoo-USA website down a few weeks ago, which seems a bad sign. VooDoo did die once before though, around 2001, then came back in 2004.
Maybe the mass market thing you mention relates to them selling the rights to the name in the UK around 2009 or so to Halfords, who now sell budget bikes using the VooDoo name in their stores. Joe Murray is not involved with that in any way though.
