Did you not read the article? It spells out the reasoning very clearly. "One key lesson we learned early on was not to charge too little. $5/month customers are just terrible. They have the highest rate of failed payments, the highest rate of credit card fraud, the highest amount of support tickets submitted, and are the least friendly people. We've doubled our prices 3x since then, and each time we do, we get nicer people who value the product more and create fewer problems. At this point I would never create a business ever again which charges less than $10/month."
