I find these nefarious intention theories shallow. It can both be the case that the endstate is them owning the means of production without that being the intended guiding goal. Companies can chase profit without being Leninistic boogeymen.
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.
