For the non-bleeding edge they have a lot of competition with more competitors showing up every day.
The way this is playing out is not surprising, it's similar to any other technological breakthrough as it becomes commercialized. Eventually those means of production will become commoditized as well.
However the result is exactly the same, concentration of power.
Also about "creating" means of production, these companies actively try to sabotage this as another profit maximization strategy. They buy all the ram, so others cannot compete. They buy startups who succeed, so they stop competing.
It's not aspersions, it's just describing the phenomenon.
Even if I take your suggestion to heart, once my company would be big enough, if I wanted to optimize for profit, I would have to do the same as these companies.
The end result is concentrated power.
