First, let me say that I agree with much of what has been said already on both sides of the fence.
I think one way to look at this is that in the world of databases, for compression to really pay off in savings, it has to be "well integrated"
into the RDBMS, not just laid on top where the first thing you have to do to use any previously compressed data is to uncompress it. We all know
that way generally does not work well unless space consumption is so onerous that you have no other choice and you can live with a potentially
draconian performance hit. It really was not that long ago that was pretty much the status quo and its really only been in the last year or two
that the RDBMS vendors have started to begin to deliver compression that was more than just superficially integrated in the RDBMS environment.
In a nutshell, if that premise holds then I think the issue boils down to how can any 3rd party utility hope to deliver on the promise?
