I think the one thing that solidified in my mind how backwards Microsoft is towards indies is when Bastion released the Stranger's Dream DLC/Update as a thanks for so much success. PC players just got it for free which was awesome, but if you were on Xbox you had to pay $1 because Microsoft only allows so many free updates for digital titles (in fact I believe it's only one, could be wrong). Sure that's cheap and all, but seriously? Somehow that just feels like being fleeced.
Then there's the whole issue of Fez being rendered nigh unplayable for some people due to bugs and the creator not being able to afford to patch it for a long time.
Also we have the case that almost every indie title outsells what it does on Xbox in like 2 days on Steam.
Oh, and the notion that MS was trying to bully independent studios into joining with a publisher in order to be able to launch on Xbox One.
Jeez, this list could just go on and on.
