To Decrease Development Costs?Total 27821 people made 514,367 changes (65,907,883 LOC) in Linux Kernel in these 10 years.

Collaboration in the open source community would be cost effective.

productivity: 200 LOC / person-month Changing the kernel outside the community might be much productive?

Not a reason why Fujitsu joins open source community, anyway.
