I feel like we almost need government intervention to keep GitHub an open commons, but I am a Libertarian and I distrust the government perhaps even more than the tech industry - still an open question for me.
Lock in and control by huge corporations is almost always uniformly bad. I have accepted the message of great books like Privacy is Power, The Tech Coup, and Surveillance Capitalism, and I feel pretty good about just using Google’s Gemini APIs when I need them, and lean as hard as possible on open models running on Ollama and LM Studio. There are also little things you can do like not installing apps and using web apps.

The problem are the extensions, I bash Electron all the time, yet I use VSCode almost daily because of certain extensions.
