The most destructive company that has come along in the console space has been Microsoft. It started when they brought us pay-to-play multiplayer online and continues with their current goal to remove ownership/control from the consumers. I am not saying everything they have done is bad but they are not the saviors of the console industry. I have said it before, both Sony and Nintendo have been around before Microsoft and both were innovative and price conscious during that time.
Right .. because Sony wasn't heading that way it self with the additional PS2 hard drive and modem combo that was released with FF11. that bay on the PS2 was there before Xbox was even announced or even existed.
the Difference is, MS was leading the technology while Sony was riding the wave in silence letting MS getting all the flame on its face like idiots.
Did you forget what the PS2 was called ? Sony computer entertainment system !! They were heading the same direction MS was. they just saw MS eating shit so they stopped.
Even during the PS4 release, Sony was always trying to let MS go first and then ride the wave, IF MS didn't get crushed by the media during the Xbox one reveal, they wouldn't have made that video where they show how used games are going to be shared with friends etc mocking the Xbox.
Hell.. you can tell even back then from that PPP they did show during E3. the slides were made in 2 minutes lol.
Not saying MS is all rainbow and shit. but MS is far from being the most destructive. Because if they were destructive like you have said, they would be the market leader by now and Sony is selling lemon juice stands.
