There isn't inherently wrong with loving a tool or been sad when it it becomes something you can't love anymore, we are tool using monkeys after all - it is perhaps our defining characteristic.
I'd be absolute crushed if Linux (for example) morphed into something I could not/no longer wanted to use, part of the reason I use open source wherever I can is because that is less likely to happen, Inkscape is still inkscape nearly 20 years after I started using it, so is Gimp, so is KDE, they've all changed but the essence of them is still the same (so has Linux).
KDE's hard-switch to Wayland broke so many things in my workflows, from what used to be a perfect system. For keyboard expansions espansso/ydotools crash bi-hourly and I couldn't pinpoint the source, clipboard sharing between applications doesn't work anymore, global shortcuts have been limited... The essence is the same, but it is so broken that it has a real productivity impact that will require a lot of effort to correct, and would depend on upstream fixes...
Gnome. If you liked Gnome 2, by now you're crushed. At least you can use Mate Desktop.
Well yeah, and there is KDE 3 which was awesome. But for most of the projects their point stands.
