Oh boy, title starts with "Open Source vs Commercial", and then the article entirely talks about paying for hosting/support/... or not, as if that's the same thing...
Note that this is about free software as in "free beer". The
original title of the article is clearer in that regard.<p>That said the article is mostly the old "OSS is only free if you
don't value your time" mixed with a couple weird assumptions;
for example that free OSS and paid (support) services exclude
each other.
