People in automotive forums and other forums and hobbies think that also,
partly because they read stuff by Hams. Many people wrongly claim or think
"conductive" grease (which isn't actually conductive) aids connections and
dielectric grease insulates.

Dielectric grease has been used to preserve electrical connections in low
pressure connections and high pressure connections at least since the 1960's
or early 1970's.
