GitHub blocked my account and they think I’m developing nuclear weapons

The US is flailing incoherently. Most of it's actions are ultimately making it weaker. It's blown all it's its international credibility. It's spending about 50% of it's GDP on a worthless security state and rent seeking. And this sort of thing is tossing the US's corporate credibility in the fire.

The US has laws that specifically sanction Iran. Companies in the US must follow US law, or risk serious consequences, and so they're following the law as required. That's it. The blocking doesn't have anything to do with whether or not you're developing a nuclear weapon, or if the service is free. Details here: https://www.treasury.gov/resource-center/faqs/Sanctions/Page... which say: "630. Is the provision or delivery of goods or services to an Iranian counterparty after November 4, 2018 allowed? [No, ] The wind-down period has ended and the United States intends to fully enforce the sanctions that have come back into effect. The provision or delivery of goods or services and/or the extension of additional loans or credits to an Iranian counterparty after November 4, 2018 — even pursuant to written contracts or written agreements entered into prior to May 8, 2018 — may result in the imposition of U.S. sanctions unless such activities are exempt from regulation, authorized by OFAC, or otherwise not sanctionable. The United States maintains authorizations and exceptions under U.S. sanctions that allow for the sale of agricultural commodities, food, medicine, and medical devices to Iran by U.S. persons and non-U.S. persons [in certain cases]."

GitHub provides a service that is not "the sale of agricultural commodities, food, medicine, and medical devices". So under US law there must be an attempt to block services to Iranians.

It's very reasonable to discuss whether or not the US should do this; argue away! But let's focus on what's actually happening, and not some irrelevant strawman argument.
