Traditionally, many style guides define components as atomic components, which are then used to build more complex molecules. In theory, this works well to create coherent and flexible systems. In practice, however, what often happens is that these re-usable atoms are used many different ways, allowing all kinds of molecules to be created. Again, this opens the door for all kinds of disjointed experiences and makes the system harder to maintain.
Many landlords have complained and resisted long-term tenants who sublet their rented space on Airbnb and profit from it without consent from the landlord. In many cases, landlords cannot instantly evict their tenants for subletting because of rental laws. A similar law in Quebec that protects tenants also does not hold them legally eligible when subletting their rented spaces as landlords would in the case of long-term rental. In 2016, Airbnb offered to work with landlords whose tenants list their properties on and launched a program consisting of mutual agreements for subletting if the landlords agreed to it and that it was legal in their local municipalities.
