Note that with just pihole you would still be affected by this, since pihole needs an upstream dns server to get it’s data from.
But if you set up pihole with unbound you will be OK, since unbound then will do the job of getting data from the root servers without another upstream dns.
I my experience it is also faster.
The thing here also is that I can’t see that they have taken into account that they deliver data center services globally.
So say that my company have 100 VMs in azure. That energy usage should count for our company and country, and not Microsoft.
