I don't agree with you that good is purely subjective.

But, in practice, what is good is highly contested, and open to philosophical and political debate. In some ways, something which is objective but very difficult to know with certainty is difficult to practically distinguish from the subjective.

If I am running an open source project, I would like to welcome contributions from people who have widely differing ideas of what the "good" is. Participation in the project should not require a general agreement on what is good, or even a general agreement on what the good is (in philosophical terms), simply an agreement on the bare minimum of shared ethics necessary for the project to successfully function.
