Not sure what you are talking about. As far as I'm concerned, every time a title will be a locked down exclusive, no matter on what platform, I will be quite disappointed about it.
As I said this is not really about cheerleading for a brand rather than another.
abadguy wasn't talking about you specifically, but "people". You replied with what read as a defense of those people, and I commented on that, not your personal stance on the matter, which I wasn't even familiar with until now (that said, I never saw you complaining about a Sony or a Nintendo game not being on PC as well, whereas you often complain about Microsoft, but it doesn't really matter, and maybe I just missed it).
Beside, neither Sony or Nintendo had Windows and an empire built over open platforms in their background, so yeah, there IS a somewhat rational reason to be more hostile toward Microsoft in that sense.
And they are still the most open to letting their games appear on PC (and other platforms), by far. When it comes to gaming, Xbox is still their flagship product, the one that built Microsoft Studios into a publishing force that it is today (despite their decent pre-Xbox game publishing efforts), and the one that's most beneficial to them since they control it in its entirety. It's nice to wish things, but expecting them to undermine all that by not keeping certain key games exclusive to the platform, at least temporarily, would be incredibly naive.
