On a day to day basis I work with Cisco, and with their product lines. While they don't open source their own code, they do showcase how relevant Linux is as a platform to deploy critical network systems on.
They are moving everything, from routers, to firewalls, to voice system on Linux kernels (as well as providing the proper credit). From this foundation they run their own proprietary code. Their is nothing ignorant or hostile with using and crediting open source software, while still retaining intellectual property rights to your own software.
As Cisco's CTO Padmasree Warrior has led many changes inside of Cisco.
1. Green DataCenter initiatives - She has led the charge in lowering power consumption of existing DataCenters by utilizing new technologies, as well as consolidating sites. This has a direct financial impact, as well as being good for the environment.
2. Focus on collaborative tools and teams - she has really pushed to break down the silo's between teams by providing the tools and technologies to seamlessly share information between teams.
Most importantly, she is a forward thinking technologist, not a bureaucrat. If I am going to trust anybody to drive the technical vision of the federal government, I am going to trust Padmasree.
