The deb version is a pointer to the snap in their repos. Nothings being replaced, it no longer exists. The deb version of Firefox in Ubuntu repos is a wrapper that installs snap and has no binaries in it. Has been for 3 years or so.
I'll note that a number of groups and forums send mailing list like emails (google groups, django dev being a big one) and that notifications can be threaded from places like Github with the right client.
Thunderbird has good threading.
Roundcube webmail is also capable here. Though when I have had it working it didn't include sent messages... which is not great in my mind.
An interesting caveat I've found for self-hosting is that getting server hardware in Canada is harder now that several companies, most notably NewEgg, have decided that any equipment that might have a business use case requires a business account and license, meanwhile Americans can still buy things like rackmount hardware no issues.
You can still get rackmount stuff on Amazon, but fuck Bezos. I'd like a better option. I've found some places like AVADirect that will ship to Canada, but not any Canadian businesses that sell that stuff to normal Canadians.
Best way to understand is to get the mental image of spacetime as a 3d sheet like grid, where each object pushes down on it and creates a pit, or well. The bigger the object the deeper the well, and the more force you will need to stop yourself from sliding towards the object and propelling yourself back up the slope.
KDEs vision is letting users have the experience they want. You can have a vision without limiting configurability and cramming bad UX down the pipe to your users.
I used Gnome Shell 3 for 4 years before giving up on it and going to KDE.
The huge differentiator is that KDE may look like windows OOTB on most distros, but if you want you can easily make it look like Gnome, Mac, Unity.. whatever. The panels and menus are infinitely configurable.
And that is why this meme is dead on the money. I've come to hate dev teams that have "visions" that they cram down users throats regardless of the experience. And the irony is that Gnome 2 used to be much more configurable than older KDE versions.
This is the one I was looking for. So famous its been used in numerous games.

Worked in most of the TMNT games too.
