Farmers getting access to diagnostics for their tractors
Not having to buy subscription-ink (looking at HP here...)
Standardized charging systems (USB-C) over proprietary cables like Lightning.

We really need more open access to the hardware and software of products on the market, and certain behaviors should not just be illegal, but require a maximum month-long turnaround to producing a commit that fixes the problem or face automatic daily fines until it is fixed and rolled out to all customers.
Seriously, I suspect this could be fixed by most people on this forum very quickly.
