I had never heard of the 'font override' option and was using Stylus in Firefox. That option together with minimum font size are a game changer for me. You've made my day, thanks!
I have a Sonos Play:1 speaker from 2013 still working perfectly with no plans from Sonos to change that. My Nest thermostat from same year will lose app and home/away features which I would say is over 50% of its current functionality, for a device that I bought for 250€. I wonder what Tony Fadell thinks about this.
The feature of reducing latency that causes different people to overlap each other when speaking seems quite interesting if they managed to solve it properly.
