In this thread, everyone getting caught up on the first toot and not the second where he clarifies his point.
If you step past the initial investment of buying a house, the analogy makes perfect sense. When you rent an apartment, your landlord (the provider) takes care of all the maintenance; you just live there and you get what you get. When you own a home, you take care of all of the maintenance, but you get to set the place up however you like. This isn't that different from a lot of FOSS out there.
