Influx of Glare?

There's a huge number of Giveaways of Glare on SteamGifts right now, which usually means the game has just become available free or hugely discounted (such as in a bundle). Yet Steam has the game at full price, IsThereAnyDeal says it's lowest current price is $9.99, and it isn't in any current bundles.

Where'd the influx of this game come from?

EDIT: Ok, so I missed a previous thread discussing this, and the free copies people are gifting are coming from IGN Prime.
