If you haven't heard of SOPA, the "Stop Online Piracy Act", read this first. Essentially, though, it provides a mechanism for corporations to "disappear" websites, quickly, with no meaningful recourse.
Several automakers are in a group, the Alliance of Automobile Manufacturers, that supports SOPA.
Those manufacturers are:
If SOPA passes, VWvortex's domain could actually be blocked from the US, for sharing various information that automakers don't want out there.
- Ford (which also explicitly supports SOPA)
- General Motors
- Land Rover
Might be a good idea to contact your representatives in Congress, if you live in the US, as well as contact these automakers to put pressure on them to denounce SOPA.
