Funnily enough, I wouldn't have seen the above message had you not

As I understand it, the LBE implementation supplies fake data, instead
of causing exceptions to be thrown. Eg, it will return a fake IMEI, or
an empty contact list etc. I've not had it crash any apps for me.

The reasons are mainly down to usability. When you install an app
through normal channels, LBE Privacy Guard sets sane defaults. Eg, it
will set access to location to be "Ask", so the first time the app
attempts to access my location a message will be popped up giving me the
option of allowing/blocking and remembering (or not) that decision.
It also lets you block access to the network per app, and it lets you
set permissions depending on wifi or 3g per app. This is important as it
is a lot easier for end services which are regularly polled to track
your location and behaviour if you're constantly popping on and off
different wifi networks (work/home/coffee shop etc). If you only connect
via 3g, then they're able to determine much less about you. Of course,
if you're using Orbot, that's even better.
The user interface is extremely well polished for an app like this too.
It is easy to see all of the apps that have permission to send SMS for
example at a quick glance, and whether or not LBE is blocking them. It
even displays how much bandwidth each individual app has used over wifi
and over 3g separately, with graphs. I can see how many times each app
has attempted to access some data, eg my call logs, and how many times
it has been blocked from doing so.
I completely understand why some people may not feel comfortable using
it though. Thoughts about the software being evil *have* crossed my
mind. I would be much happier if the source code was available. Even
happier if stock Android or Cyanogenmod had these capabilities built in.
I will stop, "shoving it down everyone's throat quite intensely," now.
