Earlier quoted context omitted.
Facebook is not your average workplace. If your platform is profiting off of active political misinformation, you have an obligation to not only discuss these issues, but solve them. If you determine that you can't solve them, it's time to stop accepting the money.
Most employees at Facebook are doing nothing of the sort. They are working on databases and internal tools and changing the color of buttons. If you work on an integrity team then yes, you'll have to discuss such issues, but most employees don't.
Maybe you're right and developers at FB don't see that they have any responsibility or input towards what FB does with the tech they build, but I hope not. It would be horrible to be that detached from the outcome of your work.
