I do agree with what the article states, but I feel the author misses on a key point. Google was based on linux and grew around it. As Google grew, they needed more linux boxes and started to develop more. They built their entire infrastructure around linux OSes and contributed most of their knowledge back to the open source world. Examples: MapReduce, GFS,... Google build it for internal, people redevelop for open source, and therefore Linux grows in usage. However, the growth in Linux could also be attributed to the boom in software/app development which theses days mostly runs on Linux anyway. Think of a big-name web or app company that doesn't use linux. Not too many I can think of.
