That nVidia GPU issue was a design flaw on nVidia's part that nVidia refused to take responsibility for.

The problem is that normal use and wear and tear over time would lead to the GPU physically failing, leading to a non-bootable system and necessitating a whole new logic board.

Apple had a long standing special service program of covering (very expensive) logic board replacements for all of those MacBook Pros that were usually well out of of warranty¹ because Apple gave a damn about making it right whereas nVidia refused to even acknowledge the issue.
