3. Cloud services are not the future. They are pushed by corporations as a way to maximize revenue models based on subscription service. They are inferior to running local software and only make sense in the context of scalable processing power. Furthermore the security implications of not being in control of your software or data are insanely bad. Software as a service is pretty much inherently unethical in all of it's incarnations.
