It may not be bad for the buyers, lenders, or the previous owners who all profit. But even then it could still be bad for regular people/society at large if it incentivizes anti-consumer practices by financial necessity when an otherwise healthy business suddenly has billions of dollars of debt it has to pay off ASAP. In which case it sort of looks like a simple transfer of wealth from existing customers to the organizers of the leveraged buyout with no broader societal value provided like new jobs created, R&D, etc.

You have a company "funded" with its own equity and now you turned it into a company exclusively made out of outside capital and an obligation to realize the terms of said outside capital.

Before, you could have had bad years in-between the good years, now you're only permitted to have good years and by good years I mean years that honor the financing terms.

When you understand this, you realize that functionally speaking, nothing has changed really, other than that the cost of financing has gone up significantly, since the company can't rely on its own equity anymore. Now the company can no longer earn what it currently earns, it needs to earn that plus some. Hence the deal was nothing but a burden to the acquired company.

The previous owners realized the value of their shares and don't have anything to complain about. The new owner acquired control over the company they wanted. So who is left to carry the burden? The employees and the customers.
