Your logic seems sound, yup.

Though broader than the issue you're responding to, the bigger quality of note in Ubuntu, is not that it's slow (nor larger), but instead, the most issue of ubuntu, is that they're very very silly. More marketing silly than sensible development.

Better Ubuntu be slow than fast anyway. See what they do when they try go fast? Like replacing the userland with rust...

That's beyond just "ready or not, here it comes" release model madness.

It's silly.
