Whenever people make appeals like this, I wonder where it is exactly they think the political power to do so comes from. Historically, organized labor, like what’s happening at Github, is the what drives pressure for these kinds of changes and funds politicians and campaigns that implement them.
If you want a more immediate example, look at what is happening across the country right now with how cities are rapidly implementing changes to police in response to protests. If you actually want these changes, this seems exactly the kind of stuff to be doing.
