See we have problem with you using the word "faith". You could have said the same thing like this: "I'm sure MS legal department has not done anything illegal." Most of us would have agreed with you. But when you use the word faith we just find it so fuck'en bizarre.
When you are outside MS looking in you don't use the word faith. MS executives have faith in MS legal. Xbox owners should not have "faith" in MS legal.
Thats your problem then dude, faith is a perfectly normal term to use in terms of my thoughts on their competency.
You're the one bringing in all these external notions, but I'm not trying to get into a semantic argument over "faith" vs "sure"
