> The factory usage in CrawlingWorker and CrawlingDroids makes the API hard to use and breaks the Law of Demeter - instead of the worker asking for what it needs, it has to first ask for the factory and then retrieve it's collaborator from it: 
> droid.getProtocolFactory().getProtocol(uri);
> droid.getParserFactory().getParser(contentType);
> This makes the API harder to use and introduces unnecessary complexity into the API.
