This is from 5.10. Warty 4.10 was the first Linux distro I actually installed, after only using a Knoppix live CD previously. I miss those days. A lot has improved for Linux but it seemed like Ubuntu was onto something. Then in 2010s they lost their way.
The snap store not being foss is such a slap in the face. The ads in the terminal (and a few other places) are particularly egregious as well.
I bailed when they did Mir and Upstart. You could literally see their ego affecting their technical decisions, leading up to "Not Invented Here" syndrome, like you see in particularly culty software companies in silicon valley.
Like one poster said, I was an early adopter (Warty) and felt the warm and cozy 'Ubuntu' everywhere in their system. It was visionary and beautiful in it's simplicity and hopefulness. They sold out.
