All 3 companies have blood on their hands (yes even Sony). If Mama Robotnik is truly reasonable, then he will admit that even Nintendo fucked up in the past.
Would surprise me if he doesn't make excuses for Nintendo fucking up the market.
Not that I should have to say this, but I own a PS3, 360, Wii, DSiXL and (newly) PSP and love all of them. I have no problems with admitting Nintendo's own catastrophes, most recently their defense of region-blocking leaving me fuming, especially as they arrogantly tried to describe it as somehow being beneficial for the consumer.
Not to mention MS's legendary "things break", which is probably worse in context as an individual quote, than any of the individual quotes I have listed.
But collectively, from many different execs and roles, Sony's arrogance as shown in these quotes is, I believe, incomparable. That's what I have tried to evidence, feel free to disagree of course.
