Yes and no, depending on the business model.
There is a lot of really good free software out there, developed by highly motivated people, who do it more as a hobby than to earn a living from it. These people are driven by the desire to produce a better product and share it with the user community.
Even a free app with advertisements could potentially generate enough money to cover expenses. If it's a solid product and everyone likes it, advertisers will pay for ad space.
