I'm no expert but isn't this article being disingenuous about three listed disadvantages of free certs? "Short lifetimes" The free cert I'm using from startssl is good for a year not the 30 days mentioned as 'standard'? "No wildcards" But you can setup multiple domains with SNI enabled, multiple subdomains too I believe? What is stated here makes it sound like its impossible to use a cert for more than one domain. "Limited flexibility" The hosting company I use makes installing a cert easy, free cert or not, via a GUI. And even I was able to setup a cert on a VPS myself. Not sure how relevant the difficulty argument is being made here
