Housing much more directly impacts individuals than software is likely to do in most cases. What makes being a landlord unethical by default, IMO, is you're participating in the commodification of one of the most basic human needs. Inevitably, even the most ethical landlord will, at the end of the day, have to make a decision based on their own economics which can easily cause a highly negative externality to the tenant, one the landlord is not required to deal with.
