But, of course, that says the same thing. These companies are scumbags because that's how the customer wants them to behave. In this case, because it makes executing payroll cheaper for the customer, which is a highly desirable trait to the customer.
IBM for example waits to fly you out to orientation in Armonk before they show you the binding employment contract with dubious clauses.
These businesspeople know this. Introducing pressure and a sense of inevitability of poor conditions is part of the game. And they know that it's scummy. But Ayn Randians will defend them to the grave as they eschew the responsibility to build a stable enduring economy for one that disproportionately rewards them.
Framing it as the customer wants this level of strongarming is the same as saying they want bloody revolution when it inevitably follows. What customers actually want is for scumbags to be banned from leadership roles in the economy, and for toxic business strategies to be regulated out of relevance.
