its simple you are saying Microsoft is harmful to the gaming industry, I asked for your reasons and you gave me a lot of reasons I will give you that, but the reasons you gave Sony either started or does every one of those reasons. so its unfair to blame Microsoft for the practices they do when Sony do exactly the same.
the hack you ask, well you brought up the pay wall for online gaming. well I agreed Microsoft did it and yes they did it first. Sony had a free service for online gaming, and unfortunately that came at a cost. less security and was hacked and a lot of data stolen, the service was shut down for a good while.
now the fact Microsoft had the paywall had them having more money to pay for the server costs and better security. I suppose you get what you pay for really
