I'm not sure why we should care about the share of money they command, as it could have nothing to do with whether they're dominant or not, depending on how skewed the market it.

PS: to note, I was commenting on the process, but on the deeper point, Dream Unlimited is only one of the company caught in this, so we could have any number of other developpers roped in at a later date. I think we really don't have any idea how widespread the issue is.
