CentOS users are not happy and are against this decision
A lot of CentOS Linux users and developers are disappointed about this decision. Many frustrated users have commented that they were expecting this since IBM bought out Red Hat.
Also so many users are thinking to move to different distributions that provides long term support. The most suggested alternatives by the users are FreeBSD, Debian, openSUSE and Ubuntu.
