* Taking screenshots requires to click the preview in order to copy to clipboard, which also causes to save it to Desktop.
No, it doesn't.
* Surprising lack of apps in the store
Says someone defending KDE? But hey, strangely enough I'm typing this in Firefox. I've got Teams running, and Zoom. There really is more than one way to install an app.
* The stupid amount of app icons in the "tray" bar. Not collapsible, not hideable.
What does that mean? There's no tray bar. Is it the menu? Is it the Dock? In both cases, it's untrue, or the writer means something else.
* No easy way to open a path in Finder
Cmd-shift-G or Go > Go to folder isn't easy enough? What's KDE's super brilliant solution?
* Finder: no side by side view for easily moving stuff between unrelated folders/paths
Can't open two windows?
And even if all were true, it misses so many other points, it's embarrassing. What OP means is: I've got a fixed workflow, and now I have to learn a few new shortcuts.
