Don't bother reading the Russ Andrews link, I have summarised it below.
Mac OSX Amarra/Decibel → Musical Fidelity X-Can V8 → AKG K702/Grado SR80 Headphones
WD NAS → Naim ND5 XS → Densen B200 Pre → Focal CMS 50's
Squeezebox Touch → HRT Music Streamer II+
Also Rega P3/Rb300/Ortofon Blue → Pro-Ject Phonobox II → Amptastic Mini-T → Ruark Talisman II
What does this do?

Reversing the polarity at the plug is potentially dangerous.
If there is a line to earth fault and the fuse is in the neutral, the fuse may blow but there will still be live voltage going into the appliance (unless the mcb trips out at the fuse board).
Advising anyone to play with this is stupid at best.

Correct!
While the equipment may well have an internal fuse it'll now be being fed by the Neutral line which is or should be at earth potential. This means the the only protection will be the fuse in the mains plug - which is generally rated far higher than an internal fuse would be for a lot of equipment
This thing is simply asking for trouble

Also, the equipment on/off switch will usually only be in the line (live) circuit. Reversing the polarity will put the switch in the neutral. That means that there will be live voltage in the appliance, even when switched off.Correct!

How can it be legal to sell something that would advise you to make such changes?

It won't be a problem with something that is double insulated.
IE anything that has only a two core cable like a bit of kit with the figure of 8 plug pictured.
In anything else it's a bloody liability
