Well when you are in charge of something that concern millions of people, you better choose your words carefully. Especially when there is a lot of anger in these people.
Sure he does have the right to think that the "always online console" is the future and the right to say it. But then there is the manner to say it and when you are in his position (a leader with some influence) and tweet like he did (in a childish manner) it will obviously create trouble. Many people felt insulted, a patronising approach was probably not the best idea. Not only referring to the famous #Dealwithit tweet but some other of his tweets too.
Maybe he didn't mean to be patronising but then he don't really know how the web and twitter works and it's still his own fault in the first place.
This is what i don't get, i'm myself on twitter and i get insults sometimes like i believe everyone already did get some at least once. And i represent nothing with my 550 followers. But i don't think that it's everyone who insults, it's just a little minority, we all know there are trolls, idiots and some extremists, don't take it personnally and just ignore them.
Of course in his case it reached a broad audience. But we have to keep in mind that even 0.1% of 1 million people still make 1000 people. Surely that so many angry people insulting you day and night can give you the terrible feeling that the whole world is against you. And a few angry people will always make more noises than many happy ones, not only on internet but it's everywhere like that. It doesn't change the fact it's a minority and once it became viral a lot of trolls who probably doesn't even care about video games come to make it worse.
Anyway he seems to not understand this or maybe he's a very sensitive person. But in his position i would never have tweeted and answered to people like he did, knowing that it would only make things worse. I don't make excuses for the ones who verbally abused him, he's probably not a bad guy but he seems to me a bit childish.
