It's up to you, of course. But I think you're making a mistake in assuming it could, in any way, benefit you as a customer. This isn't specific to this company or the particulars of the business that they're in.

Simply put, you stand to lose more than they do and they are relentless in seeking, maintaining and exploiting any leverage they have over you. Further, any power they gain over one individual customer tends to generalise to all customers. Further further, one company's leverage is another company's right.

Not being bothered by the practice is accepting the terms set by the business. Acceptance invites escalation. Relentless.

Even more simply put, you should care because this is how you get John Deere.
