I don't see why. Passive income vs profit is not really dichotomy; passive income is a question of how much work you put in, whereas profit is how much you make relative to how much you put in. Regardless of how you structure your commitments, more profit is better than less profit.
You could argue that to be successful at generating a passive income of any magnitude, you'd be better off selling value-added services on top of a free browser rather than just selling a browser. I'd be curious to hear that argument, because the opposite seems true: making freemium work means that you need to invest not just in making a great free product that people will use, but also invest in creating enough additional value to make the sale. Thus I think wanting a lower commitment to the company actually says you should just sell the browser.
