Apple dropped Nvidia after Nvidia chips were failing en-masse in the late 2000s and early 2010s, and Nvidia tried to publicly pin the blame on Apple, even though Nvidia chips in laptops by other manufacturers were also failing.
Semiaccurate isn't a reliable/unbiased source at all and shouldn't be cited as a serious source. They're on the level of the UserBenchmarks guy as being sometimes right, but always incredibly hyperbolic and emotionally attached, to the extent that it affects their work.
RoHS solder failing was an endemic problem from that era and affected all products from all brands... for example, there used to be lots of reddit posts about people baking their Radeon 7850 GPUs too.
Apple is just an 800 pound gorilla in every relationship they enter, and they like it that way, and they can use it to try and recover unexpected costs. A lawsuit of opportunity - there would have been no point in anyone suing the near-bankrupt AMD at that point, but NVIDIA had money and it was worth trying to pump them for cash even if it was an industry-wide problem... NVIDIA is part of the industry, right?
