Plenty of enterprise users need to. There are other reasons too.

I presume 'nugget is talking about the HTML rewriting aspect of the software. Injecting additional/unwanted tracking code == bad, user-requested re-writing of content == good.

Oddly Google's Android team took a different approach; on Android 4.0+ there is no way to install additional certificates without a periodic "Network may be monitored by unknown third party" notification being presented.

Very annoying if you wish to use your own CA or add another and it is also dangerous in that it masks any cert installation by malware.
