It’s more than just centralized control.
They have the ability to arbitrarily push out Snap updates.
That’s right! Your production server is getting patched without your knowledge or consent. Thankfully they magnanimously decided to let admins delay it by a few weeks.
Linux is about control. I decide what my machine does. When it updates. What it updates. The feedback from Canonical regarding Snaps was so tone dead and condescending it made Steve Balmer look sane. It boiled down to, don’t worry your pretty little head off. We know what’s best.
I used to think that I wanted to distro hop. Turns out that what I wanted was a bare bones OS that gave me the freedom to rice in strange and unnatural ways.
After 25(!) years of battling X11, dependency hells, and the early days of desktop compositing, I finally realized that what I wanted was Arch, and a few window managers to play with. SwayWM, and now Hyprland.
Unless you have some niche needs (real-time audio encoding) or want to play with more esoteric experiments (Nix, OSTree, etc), distro hopping is overkill.
But most distros have homogenized to the point to where all you need is knowledge about systemd to go from one to the other.
Just pick your favorite, non-snap distro and hack on it.
