CentOS 7 may have been released in 2014, but the software it shipped was already quite old then.

As a datapoint, CentOS Stream 9 [0], which was released in 2021, and which RHEL 9 (released in May 2022) is based on, is already ~60% out of date according to repology: https://repology.org/repository/centos_stream_9.

Also: In computer time, 8 years is "very old". That's longer than the "mainstream support" window for Windows 7 was (from 2009 to 2015), and about as long as the mainstream support window for Windows XP (from 2001 to 2009).

[0]: CentOS "Stream" has a different release model and appears to be a bit of a rolling release as I understand it? But that would cause it to be more up-to-date, not less.
