AMD Catalyst is non-free/proprietary software
AMD Catalyst driver cannot be included in Fedora because it is not free software. Fedora includes a free and open source driver for AMD graphics cards. It is highly recommended that you use the default driver that is part of Fedora and help improve it by providing your feedback. Fedora cannot help resolve bugs in the proprietary driver and all feedback should be directed to the vendor instead.
The AMD Catalyst driver is included in some of the notable third party repositories.
