If you are a part of the SEO community and visit conferences, web forums regularly, then Josh Bachynski is a name that you should be familiar with. Throughout his career, he has always doubted Google's work policy, but only recently he got an opportunity to speak personally with the optimization and algorithm guru of Google, Matt Cutts.
Josh is a highly educated man. He holds a bachelor's degree with honours, a master's degree and a PhD in Ethics and Rational Decision Theory. Thus, his discussion with Matt Cutts is worth reading. He posted the conversation in his personal site and it basically highlights why Google's work policy is immoral and penalizing websites is an unethical practice.
In his argument, he has given the most importance to three factors-
1. The search engine giant does not have the moral authority to punish sites. Especially, using algorithms like Penguin is unjustified.
2. Knowledge Graph is nothing but a tool for Google to steal content from webmasters.
3. Google is penalizing webmasters with the help of manual actions.
These are his complaints and he pointed out logically why there are problems with Google's policy. In his post he explained how Matt replied and if you read it, you will feel that Matt Cutts accepted that Google was mostly wrong. However, this is Josh's version and he may have manipulated the answers given by Matt Cutts.
