As a freelancer I disagree. I get hired by clients, do a product/project, they use that product in production and/or deploy it to their users. I get paid for that phase and then either we enter a 2nd phase of maintenance or the client goes with somebody else in the future for the project needs. When I do enter the 2nd phase, which can last years, usually my work on that project is in average to 10 hours/month vs. the full 40 hours/week when was the initial development phase.

So yeah, there is a development and there is a maintenance phase. On big projects that can spawn years eventually the maintenance phase can be seen as continuous integration, which is what the article's author is talking about, and that phase can be 90% of the project budget/lines of code/lifetime but is still the maintenance phase.

As Ray says it, he is seeing this through corporation colored glasses.
