Given that affordances is defined as "the quality or property of an object that defines its possible uses or makes clear how it can or should be used," I think it refers to how modern UI designers obfuscate the entire power of a system behind easy to use functionality that is aimed at mostly non-technical users, leaving those who have the capability to mold it to their preferences and customize it at a disadvantage. I guess affordability is then a word play on affordances.
