Disclaimer: I have worked for Cisco, and no longer do so. Cisco is an engine for buying up small companies, digesting them, and extracting value from their products. It does not really do engineering or create its own product lines. As a result, it has polished the process of buying up companies, and progressively shutting them down while extracting the maximum sales value from the products that company has developed. The key thing is that this is the core model of Cisco's entire business. It's actually not too rough on the people involved - the profits of the milking machine are shared fairly generously with the people being milked - but it is all about purchasing products with "potential future value" and converting it into cash, not creating new value.
