Folks! Let's all stop trying! This random person on the Internet says it's not worth it.
What are you talking about. We spend zero effort on AI.
There is not a naming scheme. Projects can call their apps whatever they want.
So which part of all those ecosystems are you claiming Europe could not maintain? Before you answer remember that Ubuntu is European, SUSE and openSUSE are European, Manjaro is European, most Arch developers are European, LibreOffice is European, KDE is European, GPG is European... I could go on, but, with all that shared expertise, are you sure that Europe does not possess the know-how to recreate and maintain all and every part of the Linux ecosystem?
Edit: When I say "European" I mean "started in and mainly run by people based in Europe".
Eeeeh... Not really. Remember licensing guarantees the right to fork. Many developers are not from the US and I would bet that both Asia and Europe (and probably other continents too) have the know how to manage a fork.
Don't take this the wrong way. While I appreciate the tact with which you have expressed your criticisms, but you may find that your objections all boil down to "I am used to a certain set of tools and now I have to change. The new tools do things differently and I am confused and it is messing with my productivity", that is, the problem is not entirely with the new software, but with you, your workflow and your muscle memory.
I think that KDE's track record shows that devs do not remove stuff just because. Quite the contrary.
But sometimes stuff does get removed and often it is because or it is unmaintained (and been so for a while), or because it is built on some old technology that cannot be replicated in the new environment without a complete rewrite.
In both cases, the reason a feature is discontinued boils down to a lack of resources.
Fortunately, the solution is simple: do your part.
KDE is a porous, grassroots and welcoming community. Join us and become part of the effort to build one of the largest and most diverse collections of end user, publicly-owned, free software projects in existence.
I know, I know: "but I can't code", etc., etc. But there are many things you can do to help. You can help organise Akademy 2024, you can translate menus and system messages, you can write documentation, draw wallpapers, design icons, edit videos, support booth staff at events, triage and report bugs, or just donate and contribute to financially supporting devs who still have to hold down pesky day jobs that get in the way of coding for KDE... The list goes on and on.
The point is, regardless of your level of technical knowledge, the more resources you free up elsewhere, the more time the people who do know how to code will have to maintain and translate software and features in the new Plasma 6 environment.
There are KDE dragons of many colours.
