I can actually believe this. Of most of the rest of the arguments, that tend to be rather vague, and wave at implementation, or some stock related motivation (like we need TSMCs business), a lack of genuine interest in the employees that was not sold to them or the market especially effectively seems fairly believable.
Most people are there for the chips, for making great designs in silicon, and being market leaders in CPU architecture. Not running the equivalent of an offshoring division making other people's stuff.
The entire implementation has seemed rather haphazard and not sold with much real motivation. Honestly, the entire situation feels a bit like Afghanistan (if that's a bit incendiary)
Nobody really knows why they're going. Nobody really knows what they're trying to accomplish. The objectives on the ground seem vague, ephemeral, and constantly changing. There's not much passion among the ground troops about the idea. The leaders always seem to be far away, and making strange proclamations, without actually putting boots in the dirt. The information released often feels multiple personalityish, like there's far too many cooks in the kitchen, or far too many puppeteers pulling strings in every direction. And afterward you find out it was mostly some dumpster fire driven by completely different motivations than what were publicly acknowledged.
