MetaQuotes is the software developer for MetaTrader however they do not directly setup brokers, real or fake, and don't manage the individual transactions. There are many third party companies that run servers where fake brokers can pay to host their trading inside MetaTrader (i.e. Sunroc Industrial is an example). Those third parties allow users to manipulate and delay signals, charts, etc. When you down load MT4/MT5 there is likely a very large disclaimer you have to accept which outlines the terms and conditions of Metaquotes for an end user who uses Metatrader and those terms will include lots of fun legal language like indemnification, limits of liability, etc. to absolve the software maker from illegal activities preformed by these scammers.
