That's 4 years ago for a 8 year model. Apple stops supporting models typically after 7 years
Also, I'd like to note that my 6 year old Honda Civic has a recall and they are required by law to repair the issue free of charge to the consumer. I know laptop failure won't result in potential death, but customers should be protected from poorly designed products that fail. No other laptop or desktop I have ever used has had keyboard issues.
