Right. That's a forgery - a lie. No blockchain could prevent that type of lie. What a blockchain could enable is honest transparency.
An attempt to pass off a lie as truth would be much more damaging to a company's reputation than would be just not addressing an issue. By addressing the issue and introducing a channel for transparency, the company is demonstrating that they are willing to put their reputation on the line.
I would agree that as a regulatory measure, this would not solve any problem. But as a self-imposed measure, it builds consumer trust.
