I find this very disheartening news. It obviously doesn't affect Unretrofied since it runs on Squarespace, but I do have another project that's currently hosted on (mt) and I will likely be looking into other options.
It's not that I have anything against Media Temple — in fact, I think they're super nice folks and they've been very helpful getting my other project started. But by continuing to support them, I am by extension supporting GoDaddy – historically one of the sleaziest companies on the web – and that doesn't sit well with me.
Update: Shawn Blanc takes a slightly more optimistic view of this announcement.
