Agree with OP that Intel was probably too deep into its downward spiral. While it seems Pat tried to make changes, including expanding into GPUs, it either wasn't enough or too much for the Intel board.
Splitting Intel is necessary but probably infeasible at this point in the game. Simple fact is that Intel Foundry Services has nothing to offer against the likes of TSMC and Samsung - perhaps only cheaper prices and even then it's unproven to fab any non-Intel chips. So the only way to keep it afloat is by continuing to fab Intel's own designs, until 18A node becomes viable/ready.
