It's not "broken". It's a Canon design decision. Linked spot metering is a feature on the 1D X series cameras. It isn't even available on the R3 from what I can see in the manual (I don't own one).
This is a function of software design. The word "broken" may be too strong, so I will submit that it is "illogical". The camera does a great job of catching focus for eyes, heads, bodies, and cars anywhere in the frame and then forces metering in the center. That is irrational.
My GPS will give me a route to any address. But if it insisted that the starting point is always my home address, I would be very dissatisfied.
I photograph wildlife in motion - birds and animals. For metering, I have to use full manual, and make a best guess on metering.
Fix the software guys!
