Yeah it is a strawman argument. What's your point? It was meant to be. Considering that the term "evil" is whole based on perspective a strawman seems justified to further illustrate my point, that's why I used it. There is not "logical" definition for evil as there is not definition on where "evil" begins and ends. Without defined parameters one can only attempt to define an act based on the other acts categorized with it. Since slaughtering kittens is generally seen as evil I can only conclude that terminating Reader is the same as killing kittens.
I trust you'll note that there are no fallacies in this argument, I checked. However, your rebuttal has a few. Your Black-and-White fallacy that just because Google has "stopped being such a bold defender of the open internet, and open source software" is used to put Google in as " falling in line with general tech-corporate Americana" when in reality that argument paints the situation as one or the other and not simply a business looking at being able to keep good projects open and focus on other projects by terminating some projects. Also, your "appeal-to-authority" fallacy in your statement "Just a couple days ago, a story on slashdot opened with the phrase '...a post-don't be evil google...'" shows that you believe a non-edited public created content system like /. is an authority on subjects such as this, when these are really just people opinions. I can confidently assure you that there is no scientific fact behind the idea that Google is evil or being evil.
Lastly, just because people put their time into creating things around something Google gave them doesn't make maintaining that service a requirement for Google and doesn't make the actions of Google or any company or their actions inherently evil for no longer supporting it.
