They've snapified coreutils too, and rewritten them in rust (uutils). It's proving to be a challenging transition...

Edit: While the article mentions rust's vaunted memory safety as a driver, I can't help but notice that uutils is licensed MIT, as opposed to GNU's coreutils license being GPL v3.

While snapd is licensed GPL v3, it's important to note that despite the 'd' suffix, it's barely a daemon. It's mostly a client for the snap backend - which is proprietarially licensed and only hosted with Canonical. The snapd client could be replaced at any time.

Because their sandboxing format subtly breaks so many applications (more than flatpak) and Canonical very nefariously co-opts your apt install <package> with a deb package that's actually a stub to install the Snap version, so when your shit breaks, you can waste hours before you realize that they fucked your installation.

Beyond that, Snap cold start times (installations or updates) are slow as shit (yes, even with LZO compression), and since each snap application can update on its own, you'll also encounter random times when your shit appears to "freeze" but what's actually happening is Canonical is busy polluting your loopback devices to decompress their shittified version of your app.
