Jira is a product which serves two masters - one are development teams which use it to track bugs, tickets, projects, etc. The other one are middle management types who use it for project tracking, reporting to upper management, tracking metrics of different teams (no matter how dubious) etc. The people who decide which software gets adopted internally generally care about the latter, and thus Jira is selected, and thus Jira grows to their needs - where complexity is often a bonus, and poor day to day performance a minimal concern.
