No corporate consolidation is how you end up with companies like Sony to begin with. And even then, they’re funding the creation of new pop culture while this is Microsoft wanting to grab up existing culture so they can profit from it. One is an example of something being created and the other is something being hoarded.
Any short term benefit a consumer sees from consolidation is simply a cost the corporation pays to achieve a scenario where they no longer have to provide those benefits. Microsoft is already very well know for the Embrace, Envelop, Extinguish strategy so assuming good will on their part is painfully naïve.
Corporations are not your friend and don’t care about your well-being, they just want your money.
Why do you think corporate consolidation should happen? Every time it does it benefits the corporations and never the consumer. Anti-trust is incredibly important to keep business from taking control of aspects of our culture and socialization.
