just out of curiosity, what's wrong with the more 'traditional' Linux desktops, such as Plasma or Cinnamon?
A lot of the issue is that you were able to name more than one, and that was without mentioning Gnome or XFCE
for them, taskbar on bottom + 'start' menu = "neat, i already know how to use this!"
personally, i use i3/sway tiling window managers, and also keep gnome around if i want a full desktop. personally, i love the amount of choice we have in the gnu/linux world. if something doesn't work for you, you can select from so many other options.
"but...but...fragmentation! those guys working on cinnamon/mate/etc should just join gnome or kde and make The One True Desktop!" eh. i don't buy this line of thinking.
