code, and package it into a solution, but they are honest about the origin of the software. They always credited the author, and follow the license that governs the source code.
Hat distribution is always free of charge. You can download the ISO and install the OS. It is still the same today. You only pay if you want their support and patch update.
software is licensed under GNU GPL. This effectively requires other people who takes your source code to release their enhancement under the same license, if they are giving/selling it to a third party. This stops people from making the software proprietary and the software becomes better each time it was modified. Your rival becomes your friend.
Hat hires most of Linux kernel maintainer. Red Hat produce Fedora distribution for the community (and as their testbed too). Red Hat buy rights to proprietary software and made it Open Source (Netscape Directory Server). Red Hat support emerging technologies (KVM, libvirt, augeas)
Source is that you can collaborate with your rival. Red Hat and Suse collaborated together for LibreOffice development, and in the end, both company (and community) get the benefits
also patented their invention. But they don't use it to extract money from other company. In fact, Red Hat use patent to protect themselves and others from patent troll. Look for Open Invention Network
bit Red Hat focus is always Linux operating system, but that does not stop them from diversifying their product to include Java Application Server (JBOSS), Cloud (Red Hat OpenStack) and storage (GlusterFS)
clones is everywhere. CentOS, Oracle Enterprise Linux and Yellow Dog Linux are some of them. This clones might produce something that could be good for you. For example YUM package updater comes from Yellow Dog, and now the default tool in Red Hat and other clones
