Why does the DS hacking suffer as much as the PSP?

[okr]

The DS has a different audience than the PSP.

There are millions and millions of DS owners who don't even know how to pirate a DS game (including myself).

I once bought a R4 cartridge because I wanted to try out some of my old point and click adventures via ScummVM on my DS (and surprisingly it worked fine). I got the tip about R4 and ScummVM compatibility from a DS homebrew blog. Later I read in some VGChartz thread that the R4 cartridge is used to pirate games. I still don't know how it works and I don't want to know. Until today the only games on my R4 are my old LucasArts adventures and some mildly interesting homebrew stuff.
