1) Because it is awfully slow (160 msec, for data in the cache),

2) Because it decreases reliability (if I use OpenDNS and the transit
links of my provider, Renater, goes down, I cannot even resolve ".fr"
domains),

3) Because it is broken (see the "NXDOMAIN with some types but not
with others" bug),

4) Because security issues are "addressed" by vague claims.

There are other reasons but they were well explained by Paul Vixie.
