Kickboxing vs Muay Thai: The same but different

An old training partner of mine posted this on the Facebook this week. I thought it was a pretty good article but was wondering how accurate the analysis of various styles are? I learned a traditional style of Muay Thai and their description seems pretty good of that. I don't have much knowledge of the other styles.

I really wish they would have talked more about Chinese kickboxing too. Would have made the article even more interesting.
