I work for Google and Google has a lot of products that has improved my life immensely. Google maps, Google search, Google docs, gmail and Youtube are all very useful products, especially for poor people who can't afford paid options. I don't feel bad in the slightest for working to improve them.

People say that Google does questionable things but I haven't seen any of it. Of course as a bottom-up organization it is very likely that other parts of Google are less ethical but that doesn't really affect my work or conscience.
