It's not because they die more than usual (likely less than original ones even) but it's because each of the dead GPUs Cablemod has to cover and it's simply much cheaper for them to recall the whole batch than to later repair/replace even just 1% of the GPUs. It's just not worth it, bad business. More brands could take the same route, as it's cheaper and that connector will always cause issues.
Also, I just watched new videos from NorthbridgeFix, like this one:
