The simplest explanation is that the iPod Touch 4th generation requires that the voltage coming into the docking port be exactly 5 Volts. The previous generations all accepted voltages up to 12 volts, and many accessory manufacturers took the easy out and didn't feed 5 volts, despite that being Apple's spec since the original iPod.
Why ? Lazy engineers.
The newest (just shipping last week) 5th generation has the new 'lightning' port, which is pretty much completely non functional on EVERY accessory sold to date.
