Switches that last forever would be interesting. Subscription models and sw updates for a mouse are the very opposite of interesting. I'd pay not to have either.
There are industrial switches that last practically forever. I've made some test robots for wearing out limit switches and the decent ones could be hammered constantly for days on end without a single miss.
Another component that doesn't wear out is a photo gate. It doesn't click or spring, though.
Actually just a decent keyboard switch would probably put up with a lot.
But it's cheaper to go cheap and you get more repeat business.
My $50 mouse has switches rated for 20 million clicks. Had it for 5 years and it still works flawlessly, but if they do ever wear out I can replace them.
