Well that's bad, that means it's just another centralized pool that will want to start operations in Bitcoin mining.
What do you expect from a business?
They are in for the money and for control, otherwise, this would be the work of anonymous crypto fans over github.
What will happen when all of these mining companies combined control over 50% of the harsh rate?
First, watching the mining scene for so long and being somewhat involved in it, I think they already do, they just hide that, I have a spot somewhere in the difficulty speculation about how those percentages during the texas shutdown were so weird looking.
Second, what could be, depends on what people are in charge of it, Costco or Pfizer, Balenciaga or Ikea it could be a nothing burger or really, but really bad!.
