This is horrible news and yes, you can say goodbye to the 9% commission and possibly to Dan itself, as I could see GD buying the company just to "amalgamate it with Afternic" as that route is pretty clear from the interview I read with Paul Nicks. It's all "Afternic, Afternic, Afternic" and virtually nothing about Dan.
How I see it progressing:
1) A change to 20% commission in the coming months due to "alignment with the current GD fee structure".
2) A slow merge with Afternic, with the distinct possibility of adding Dan features and automation to the Afternic network and potentially shutting Dan down (i.e. "merging the two entities into a dynamic new aftermarket engine").
Monopoly control is always bad news and it looks like GD is going to flash their wallet at all the domain aftermarket competitors and see who's greedy enough to take the bait.
Apparently the Dan owners were looking to get paid, after shoveling us all that happy horseshit about "becoming a registrar" and "system improvements" they just took the money and ran, leaving their customer base locked in with GoDaddy. Very disappointing, as I thought they actually liked being in business, and were better than that.
