which linux distro do you NOT like, and why?

For me, it's Ubuntu as well. Canonical continuously integrates stuff to make the whole distribution more complex and hard to maintain. Without going into much detail, Ubuntu always tries to do things where there is a good standardized way different. Why the heck do we need yet another containerized GUI application environment (I'm looking at you, Snap!); Why do you develop lxd, when there is systemd-nspawn, docker and podman?!
