To me, from a legal stand-point, because all warranties are void when overclocking, Gigabyte isn't responsible for any problems caused when overclocking. Neither is any other hardware company.
To me, from a consumer-realtions stand-point, it would make sense to contact all registered users of the affected products, advise them to update the BIOS, and to issue a release advising unregistered users or prospective buyers that they need to be sure to use the F7 BIOS or future subsequent BIOSes. They have already done the second part, and are taking steps to ensure that boards in teh retail space ahve teh F7 BIOS or newer on them.
Again, non-issue. But it is still good to get the info out as a precaution, and I gotta commend Gigabyte for taking such steps as they already have, rather than ignoring the problem.
