I had this problem on my MBP from 2008. I spent $175 with a 3rd party fixit shop and am happy to say it's still kicking as I'm writing this. I was pretty bummed when it happened but I'm happy to say I have a computer from 2008 that is still useful in 2014 and runs the latest software just fine.
Problems with Macbooks are not just limited to the graphics card. Many of my colleagues have had either hardware or software problems with theirs. I am not trying to start a flame war, I am just making an observation.
The Macbook I bought in 2007 was the best computer I've ever owned, and it still works! I wish I could say the same about my wife's new Macbook purchased last year. It will freeze for minutes at a time, the app store won't load, and safari will not open no matter how long we wait, so we have to use chrome.
I don't know if it would. But Apple has been pretty successful with keeping this issue low-key as of now. Maybe if enough external channels are used they might feel pressurised enough.
There's also media worldwide that's covering the issue. Apple needs to stop ignoring this defect and offer a recall and replacement program before his escalates further.
