What about services which use anycast/geolocation to decide where to serve you data from? They will get bad location data as they will get the location of the resolver. This can have a direct impact on services. An example of my own is from about 10 years ago when Netflix started streaming. We got a Roku and signed up but the service terrible due to the stream stopping to buffer every few minutes. After researching and trying several things I eventually came across the fact that the stream was coming from servers in over a thousand miles away with pretty bad latency between. Long story short, I eventually figured out it was due to my using the level3 resolvers for DNS. As soon as I changed to our ISP's DNS servers it worked great and the data was streaming from very close.
