OSS is a public good. Like fundamental research, it benefits everyone (and you may not know who,where,how for a long time), it requires long term work (longer than market tempos), and it needs freedom from economic and industry boombust cycles. So maybe OSS developers,maintainers and infrastructure could be funded by taxes, perhaps through an NGO. Many nations fund the arts and sciences and journalism and education so people can enjoy their fruits. And so no one patron or corporation directly dominates their direction or access.

Or is it moving HQs from tax-the-rich to tax-the-rest states?
