Then you have several layers of products (software titles in this case) being stacked one on top of another, until the renter isn't even the consumer of the product.
Virtually none of these places are using anything that allows them to one-off a lease for a grouchy asshole. But if renters really demanded that and wanted to pay for it, I guess there could be an onsite lawyer willing and able to vet those modifications and put the lease through. But in a day and age where every whiny Starbucks barista complains that they can't afford the 4000sqft studio apartment of their dreams, I doubt they want to pay the extra premium that would result from individualized lease contracts.
It's the banality of "you're not important enough to spend the time on". No one's being loaded into cattle cars.
