All the same privacy harms with online tracking are also present with AI, but worse. This richer personal information can be more thoroughly exploited for manipulation, both commercially and ideologically.
I think part of how we get pushed into things we collectively don't want is because we stay quiet about it.
Many of my contacts in the open source community have been talking about plans to move from GitHub to Codeberg or a self-hosted Forgejo (Forgejo is the software used by Codeberg) over the last month.
I refuse using AI in the same way I don't take drugs or steal things – for me it's a matter of principle. So if this continues and Microsoft does not provide a way to opt out of AI for my repositories soon, I will move my code to a self-hosted solution and won't ever return to GitHub.
