It's just where you build software for. Of software isn't your main product, just needed so you can better make your main product, than open source software can be very helpful for you. It's a nice way to help each other, and it doesn't change your profit. But if software is your main product, than is open source very hard to pay your bills. Also if you build software for a company, very few will pay for something that will be shared to everybody. But I know a hospital that pay to write software for some hardware on Linux, and share it as open source so all hospitals that use that hardware with Linux can use it. That is helping other people if you have solve a problem. Buy indeed, open source isn't a business model, but a way of life.
