How Apple's subcontractors' technology is stolen

First, they outsource to a subcontractor.
Then, they identify the subcontractor's technology
and create their own specification documents.
These specifications are very similar to the subcontractor's technical specs.
Since they provided the specs, they claim ownership of your IP.
The subcontractor cannot refuse because it is a massive contract.
Based on the spec documents, they demand the sharing of detailed information.
During the verification stage, the entire technology is leaked.
They repeat this 3-4 times through spec upgrades to steal all technology.
Then, they either run their own in-house development team
or leak it to China.
