Technically, a warranty covers manufacturing defects such as this. They did extend the warranty of customers. So, legally they did everything they were obligated to do, even if they did not communicate the extension.
This is not to be confused with a recall situation, where a product poses a potential safety hazard... like exploding Sony batteries (Yeah, Apple sux! HeHe!).
I know we all HATE Apple here at Tom's, but seriously, these people had their laptop for a minimum of 3 years with a warranty to fix the issue. Personally, if I do not upgrade the memory in a "laptop" within the first two, it is never going to happen. Consumers who chose not to contact Apple with issues... well.. meet Darwin (not the Apple OS).
Face the fact, Mr. Gomelsky is either stupid, a scammer, or both. Why should Apple make him rich?... When they could make you rich for hating Apple?
