The climate costs aren't "insane". One billion devices receiving the push (probably an overestimate) represents about 0.02% of global internet traffic.
The guy kind of proves this in his own post. The annual emissions of 13 000 cars (which is what this would equate to on 1 billion devices) is fuck all on a global level. One city pushing for bike-friendly infrastructure will have 10x that effect.
This is not to say this isn't kind of a stupid update, but the only thing insane about the climate costs is how insanely contrived bringing them up here is.
