Nothing prevents a paid product to be FOSS. What I am advocating for is making Firefox users also become its customers, vs current situation where user!=customer, and customer being Google. This obvious and giant conflict of interest has to be a major contributing factor to the decline of Firefox. I am aware that Firefox may lose 90% of its user base if it switched to a paid model, but my point is it will do so eventually anyway - if things do not change radically.
