When a vulnerability is found in Flash, it usually impacts all browsers. On the other hand, HTML specifications have different implementations for each browser.
They can still just target Chrome, and get over half of users. I suppose Google figures that gives them more control over searching for and patching vulnerabilities though. On the other hand, if Flash is no longer enabled by default, then it's no longer as much of a security risk for those who continue to use it either, since fewer people with malicious intent will bother searching for exploits in a piece of software that relatively few people have enabled.

That $5 coupon is going to save them a lot of lost sales until they get their HTML5 redesign up.
Plus, they're actually likely to make some sales out of this that they might not have otherwise. If someone was going to ship something using another courier, but they heard FedEx is having a "$5 off $30 sale" for simply toggling a setting in their browser, I'm sure there will be people who will jump on that. They might even make some new regular customers if they find that they like the service.
