Quotes from the article that were available to me:
"Note that after 2013 and release 3.5.13.2,
Trinity switched its numbering system to avoid being dismissed because
of its version number alone."
The above statement is absolutely untrue, at least for me. I genuinely feel sorry for any user that picks a desktop because of a version number, rather than functionality.
As to functionality, TDE is faster than KDE Plasma, and actually displays folder contents the exact way I want to see them. I don't want to see a mix of folders and files when I am browsing the file system. Gnome seems to have banished the use of desktop icons, forcing the end user to remember the name of the application they want to use, so they can search for it. A lot of desktop space is wasted and time wasted searching rather than just clicking on what you want. And sometimes the command line for an icon should actually be edited. In Linux, sometimes, it is important to modify things so you can do what you want and how you want.
TDE does not lack an application search function. The only things I ever borrow from other desktops, that works well in TDE is are 1. network manager[1] application and 2. KDE connect.
"Trinity is included in few distributions, so the project cannot depend
on maintainers from outside the project. Instead, the project includes
downloads for images of several distributions configured to install
Trinity. These include a number of images for Debian, Devuan, Red Hat,
and Fedora. For convenience, the Long-Term Support (LTS) releases, such
as Ubuntu 20.04 (Focal Fossa), are probably the ones to choose because
newer releases may not support Trinity. In some cases, unofficial or
testing versions may also be available. Yet another alternative is to install from source tarballs, which is the
only choice for adding Trinity to an existing installation."
This is an unclear statement, but I personally know that there are several repositories for several distributions.
Oh wait, they added this later:
"Unless you install from source files, the installer for Trinity depends on the distribution used."
I really don't see how making images available for several distribution should amount to a criticism.
[1] I rarely use network manager because it has, at times, interfered with Postfix functionality, which I use to send fail to ban notices on desktops I have a way to remote into to administer.
