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).
