You do not owe anyone an apology for choosing to sell something. You do not owe yourself an apology for choosing to sell something. You do not need to mention the economy or your personal economic circumstances. It will not successfully motivate anyone to pay you a thousand dollars. No lawyer in the country does that. No doctor in the country does that. No teacher in the country does that. You being compensated for your professional labor is not an outlandish request. It is the default. This will discomfit some freeloaders in your community. They contribute no patches or money. Let them wget the binaries; do not allow them to wget an iota of your stress budget.
