Does that make me unethical if I contribute to free or open source software, then Facebook uses that software, even though I don't work for them? Why would the answer to that question be different for employees?
No, a non-employee contributing to open-source software doesn't make them unethical; again, I don't care to lay blame at the feet of a tool.
I take it as axiomatic that Facebook is an unethical actor. I believe I have good reasons for this. From there, I say that anyone who works to make Facebook more effective at its unethical goals is similarly unethical.
No, this doesn't include people that contribute to OSS that originated at Facebook. Improving OSS is a contribution to the community, of which Facebook is unfortunately permitted to benefit from. Facebook starting an OSS project does not make the OSS unethical, because the OSS is a tool.
The question is different for employees because of this community/Facebook divide. Facebook employees are not unethical because of the tools they use for Facebook, they are unethical for furthering Facebook's unethical aims.
Good question. Is it an open source project that originated at Facebook?
On the topic of open source, would it be possible to construct a license that removes the ability of bad actors to use it? Of course, a bad actor could use it against the terms of the license, but the intent of the software project is made clear.
