I'm saying that they probably have/had difficulties with getting hw, e.g. bump with previous supplier, the one they thought to use when they opened campaign and difficulties now to find new one. But it might be bad for PR, so they described it as "updating for better" or what can be the reason to be silent on that. Placeholder in meaning "we can't tell truth, will not just hide, but clean it up with telling it's good for users"
