Fragile against upgrades, tons of unmaintained plugins, admin panel UX is a mess where you struggle to find the stuff your are looking for, half backed transition to nicer UI (Blue Ocean) that has been ongoing for years, too many ways to setup jobs and integrates with repos, poor resource management (disk space, CPU, RAM), sketchy security patterns inadvertently encouraged.

This stuff is a nightmare to manage, and with large code bases/products, you need a dedicated "devops" just to babysit the thing and avoid it becoming a liability for your devs.

I'm actually looking forward our migration to GHEC from on-prem just because Github Actions, as shitty as they are, are far less of an headache than Jenkins.
