Yes, times change. Now MS is not the top dog anymore, Amazon, Apple, Google and Facebook are all eating his lunch. There is competition. So they can't get away with acting like the old MS. The marketing people figured that out, and are just adjusting. Business as usual.
I've never seen a deeply flawed self-enclosed cultured turned into a sane one. I've seen ones change because they were so much injected with outside influenced. I've seen ones change because the core was alright, and it recognized the problem. But never have I seen a team of bullies sticking together and turn into good people.
However, I have seen plenty of them putting up a smile, getting some green paint on and buying a stairway to heaven.
It's a shame people keep falling for it though. That's why politicians can be crooked. That's why abusive relationships last. That's why you can pollute, use children workers and lie to customers: by the time you pay the price, it's a slap on the wrist compared to what you did, and earned from it.
Then you just say you changed, and people forget or forgive, let you keep the loot, and the right to carry on with your business.
