I think you'd be hard pressed to find more than a tenth of a percent of people attempt to run their own DNS server. Some do because they think it'll be better in some way. Rare is the occasion where anything user configured would outperform a local DNS server managed by the ISP that does no form of trickery.

Except that half the time people run their own DNS resolvers because
their provider's resolvers are
1) Absolute garbage and either fail queries for no reason, don't respond
at times, respond super slow, etc.
2) Hijack NXDOMAIN for advertising / money generation
3) Hijack responses to inject their own ads, popups, etc.
