Microtransaction

   Microtransaction, also microtheft, is the practice of selling -- for a
   relatively "low" price -- virtual goods in some virtual environment,
   especially [1]games, by the owner of that environment. It's a popular
   business model of many [2]capitalist games -- players have an "option"
   (which they are pushed to take) to buy things such as skins and purely
   cosmetic items but also items giving an unfair advantage over other
   players (in-game currency, stronger weapons, faster leveling, ...). This
   is often targeted at children.

   Not only don't they show you the source code they run on your computer,
   not only don't they even give you an independently playable copy of the
   game you paid for, not only do they spy on you, they also have the
   audacity to ask for more and more money after you've already paid for the
   thing that abuses you.
