If you agree with the above principle, you are encouraged to adopt measures so that a such conduct can be effectively applied in your environment.
If you are a developer, be ready to point out (perhaps in writing) that you are willing to take full responsibility of your code and for this reason you are expected in some situation (i.e. insufficient technical experience, insufficient aptitude, etc.) to proclaim the impossibility to deliver code for ethical reasons conflicting with the principle. Reciprocally, you should have the right to know the position of each member of your team about the principle.
