Man, TV-TV-TV was the least of their PR issues. "Xbox One requires always-on internet" and "developers can disable used game playback," anyone?
Yuuuup. And everyone likes to play what if about family sharing and digital trade-in, but Mattrick and the PR were so half-assed and hamfisted that nobody really knew what was being offered. Which itself wouldn't have been quite so bad if Mattrick wasn't so completely smug about it.
He absolutely damaged the Xbox brand despite going to Zynga soon after; leaders build teams around their philosophy, and that dogma takes a while to diminish.
