The Free Software Movement... was never about Free Software

This article and apparently the one it directly counters, are discussing the "Freemium Business Model", "Ad-Supported Business Model" and "Platform-Play", while discussing "When Software Should not be Free".
These things have absolutely nothing to do with Free Software. Sorry to get all RMS on this post, but I think it does a disservice to both topics (Free Software and SaaS business models), each of which are interesting, but not when confused with one another.
This appears to be about web sites and business models and not software licensing. Not that I hold it against this guy, but when we don't all use these terms the same way it gets confusing.
