It's not technically required when setting up Tor, so I think a lot of people just forget about it. When I set up an exit relay, I knew I was supposed to run a local DNS server, but I completely forgot to install it until about a month later when the topic appeared in this list.

The other problem is that Google DNS is almost always used by default in many VPS providers. I suppose it's cheaper when they don't have to provide their own servers.

Reading [1] I do wonder about that.
Why do Tor exit relay operators avoid installing a local resolver - or at least simple a cache as shown in [2] ?
Adding different nameserver= lines to /etc/resolv.conf than 8.8.8.8 shouldn't be a big thing, or ?
