It's not bloated, it just has lots of options. If you like someone else to decide everything for you: buy a Mac or use gnome. But KDE is not for you then. Don't try to make it into something it was never meant to be.
Yeah cinnamon is basically a remake of Gnome 2, from before the devs went batshit crazy and went more opinionated than Apple. It's not bad but I really prefer KDE, also because I think Qt is a much better desktop framework than GTK is.
I rather think the right word is clunky: one of the dev is attached to Server-Side Decoration/against CSD for some reason (none of his arguments make sense), so every stock app are difficult to read and taking unneeded screen space. It's just bad UX.
Are you being purposefully controversial (to not say trollish)?
To the exact contrary to what you assert, one of the prominent argument against Gnome that I've been seing times and times again in DE debates, is the "dogmatic" opposition to SSD from the Gnome project.
They're not arguing with you, they're yes-anding you. Read as "ah a one word opinionated description...let's steelman that. here's my one-word opinionated term: clunky. Here's what smells make me get that vibe. What smells contribute to the bloat one? :)"
Doubling down on short judge-y stacatto contributes to an aggressive "I don't need to tell you" vibe that would be sassy and fun, maybe, if in person. In writing online comments, it just means we need to get a 3rd comment from you before we get to anything I'm interested in (I don't particularly care what your one word description is, I don't know you)
Funny, I used to think it was bloat but then I got to use it to store passwords for remote servers accessed with ssh, and now it's a nice 'batteries included' for me, as GP mentioned. It has become so because it is nicely and seamlessly integrated.
If you think that then don't install everything under the sun or choose a better distro. You can just install only Plasma Desktop, Doplhin and the handful of utilities you actually use, you know?
