> It's fine for a project to have moral/ideological leanings
As long as they align with the correct (i.e. yours) values, of course. When they adopt the wrong values, it's not fine.
But it is fine. If I disagree with a project's values I'm not going to contribute to it, and they wouldn't want me there either.
There's still a line between values I disagree with and values that directly attack me as a person. The former is how many of us feel about some of our dependencies and most proprietary software we use, so it's clearly fine to some degree.
