How much money have you given to FOSS? (Let me guess: 0). But it's good that you are giving them your moral support here online. That's surely worth something.

If your teenager behaves like FOSS developers, then he probably won't get any repeat customers: "Hey man, I might mow your lawn or I might not. Pay me 20 dollars right now and you'll find out, maybe."

I will continue to avoid FOSS. I congratulate the developers and maintainers for all the free labour they provide to make sure the likes of Amazon, Google and Microsoft stay profitable. Their shareholders are surely grateful.

For me, I will continue to purchase high quality software from independent developers.
