The author mentions letsencrypt, but their description of why letsencrypt is not a solution makes me think they have a less than complete understanding of modern SSL.
Also the configuration issue with regard to not supporting wildcard certs is not a problem IMO. If you're big enough to require multiple subdomains the fact that you're managing multiple certificates instead of one does not need to be a logistical issue. Automation is our friend.
