Don't fork me on GitHub

GitHub core is non-free software.

GitHub has censored numerous repositories.

Commercial entities will always focus on THEIR best interests, NOT yours.

GitHub was acquired by Microsoft in mid-2018, meaning potential tighter integration with Microsoft's (non-free) cloud services and other commercial products.

Copilot is a for-profit product - developed and marketed by Microsoft and their GitHub subsidiary - that uses Artificial Intelligence (AI) techniques to automatically generate code interactively for developers. The AI model was trained (according to GitHub's own statements) exclusively with projects that were hosted on GitHub, including many licensed under copyleft licenses. Most of those projects are not in the "public domain", they are licensed under copyleft/FOSS licenses. These licenses have requirements including proper author attribution and, in the case of copyleft licenses, they sometimes require that works based on and/or that incorporate the software be licensed under the same copyleft license as the prior work. Microsoft and GitHub have been ignoring these license requirements. In addition to these legal issues, the ethical implications of GitHub's choice to use copylefted code in the service of creating proprietary software, are grave.

Despite their recent claims to the contrary, Microsoft have never been known for their benevolence.

GitHub can and will suspend your private repos if your premium account lapses.

As per their terms-of-service

Why would any right-minded individual use their service?

As a software professional with extensive technical knowledge, why would you not make use of the readily available tools to maintain control over your own code?
