Microsoft co-founder who wrote the runtime portion of the original 1975 Altair BASIC interpreter alongside Paul Allen and Monte Davidoff; his 1976 "Open Letter to Hobbyists" (claiming under 10% of Altair owners had paid for it) is treated in this vault as a founding document of software-piracy rhetoric. Fifty years later, in April 2025, he released a scan of the original 1975 source listing himself, on his own site, to mark Microsoft's 50th anniversary — the primary artifact this vault used to confirm Davidoff's credit-but-not-copyright treatment directly rather than through secondhand retelling.
