Whenever I see FOSS offered as a solution I have to wonder if that person is paying for their own food, shelter, transportation and what have you, or if they are still living with their parents and not making any attempt to support themselves.
Nothing is free. There is a cost incurred at some point. The minimum cost is time, a finite commodity for all living beings, and effort, but other things require materials, which cost someone some time and effort to find, extract, or otherwise produce.
I certainly don’t say any of this in defense of capitalism, but “free” is a nonsense concept in human life. It simply doesn’t exist.
Doing something because you want to is vastly different from expecting everything to be free.
