Morality is subjective, according to my moral framework, telling people there are 38 room left, if I'm the business owner and the benefit > cost then yes.
Same thing with slavery, extermination camp, weed. To some people these are moral.

Morality is subjective but not in the manner you're describing. It's not arbitrary. Our values are conjured out of thin air but for reasons that DO involve the betterment of humanity.
Slavery isn't subjective, and extermination camps sure as hell are not either.
How is slavery or extermination camps not subjective? The slave owner may think slavery is good thing but the slaves may think its horrible.
Whether its indefensible or not, is matter of your preference/personal value.
