Red Hat has long been the poster child of Linux and open source, the distribution that has been there since the beginning, grew up right, got all the luck, usually made the right decisions, and fetched up on top of the pile. Staying at the top of the pile may present a different set of problems. Free and open source software has made its presence felt, the operating system has become increasingly commoditised, free software is rising up the stack, cloud computing and virtualisation are transforming the market for operating systems, and open source (in some form or another) is being adopted or proclaimed by many different companies.
