The kidnapping of the Freescale employee's or their cargo is a far fetched given how paranoid the US is in letting US companies do sensitive work or even use materials sourced from China in sensitive (national security) related projects. Even a 2 dollar magnet gets flak and requires an exemption how likely do you think the US government and freescale itself would even float the idea of doing super-secret design work in china.
Freescale has many divisions and the one in China seems to be focused on what happens in china, chip fab research, RF design for cellphones, MCUs for cars and vehicles, consumer electronics, ...
The malaysia office is also into consumer electronics, cellphones, and related subjects.
See this job posting for freescale, (Note the requirements on the bottom and US location)
US citizenship and fluency in English
A valid US passport
Frequent travel to customer sites within the US and internationally (25% of the time)
Willingness to sign a DoD ITAR NDA
An active or re-activatible DoD security clearance, or no known barriers to obtaining a first time security clearance
Most of the US restrictions on technology transfer and location sensitivities are already in place just to stop such an insane plot from occurring. Which is why it makes little sense here. None of the freescale passengers likely qualify for security clearance just based on their passport alone.
If someone was going to do this they would take a flight carrying a team of US based Freescale employee's.
