(Have you noticed, too, that in the other thread people complaining about Horner repeating himself don't seem to have this same problem with Goldsmith?)
The complaints I hear about Horner are that he reuses themes from one movie or franchise in a totally unrelated one. Goldsmith would reuse themes within a single series, but it's not like he ever used a
Rambo theme in
Star Trek or a
Planet of the Apes motif in
Alien. Even when
Gremlins 2 called for a Rambo parody, he did a variation of Gizmo's theme with a Ramboesque sound rather than quoting his own Rambo themes. (Although he did use a quote of his
Gremlins theme as a gag in
Looney Tunes: Back in Action when the hero's car was revealed as a Ford Gremlin, but that was a joke that fit the Looney Tunes musical idiom.) His overall body of work is far less repetitive and more diverse than Horner's.
