TSMC, in turn, outsources the entire front end of its value chain to its customers.

There is nothing wrong with outsourcing. Boeing is just bad at supply chain management.

These factories in question build for three major Western manufacturers: Boeing, Airbus, and Bombardier.

How much though? Somewhere else in this thread someone said 67% of their revenue is from Boeing.
