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).

Gnome. If you liked Gnome 2, by now you're crushed. At least you can use Mate Desktop.
