I think you're right, but I really just wanted to focus on the zero-cost claim that I quoted from the article. Firefox is just one example of an upgrade, and the logic applies anywhere: it's a trade-off, where "never" assumes too much risk (which is an expense), and "hourly" is also a very risky upgrade schedule. The sweet spot is naturally somewhere in between.
