It's not necessarily hard feelings.  They may just not want to use their servers to advertise a competitor's products.

They've already been through this with the commercial forum.  Originally it was meant for merchants selling in places other than DAZ - to keep them out of the Commons.

But the DAZ merchants wanted to post there, too, and eventually they pushed out the non-DAZ merchants.  Because they didn't want to host ads for a competitor, pointing out that other stores like Rendo don't allow it, either.  Even if your products are for things that only work in DS, you can't advertise them there.

Of course, Dawn is free, and there's nothing for sale at HiveWire yet, so perhaps that's why they are reviewing it, instead of telling people to knock it off.
