Interesting, I have nearly the exact same situation except replace Nvidia with AMD. "Radeongate".

Also have miraculously saved the machine with a booting ritual/hack that bypasses the discrete gpu

Also 2011 MacBook.

I'm worried that you are right, and that I had an AMD card as well. I'm unsure, as the focus of my disappointment is Apple, rather than the manufacturer of the card.
