I think Avatar Press tried to expand too much in too little time, perhaps not aided by whatever financial ability they had at the moment.
2 or so years ago they were running 2 Crossed series concurrently, courting Alan Moore for a large 12 part series, and Ennis for two monthlies and Gillen for another with one of their premiere artists. The sheer size of the scaling back, very rapidly too, since then is noticeable. While I don't think they're going under, I think they are still reeling from collapsing under a weight of their own devising.
Now that Providence has ended, they've started hinting in the comments of the box set Kickstarter that they will bring back Crossed. Meaning to me that perhaps, yes, these creators were a bit of an anchor/double edged sword for them.
