Objective-C is closer to the original, or at least early, Alan Kay and Smalltalk flavor of object oriented languages. In the late 1990s, we had already had 10 years of C++, so the C++ flavor "C with classes" type of object oriented programming was more familiar to most people.
I'd guess already then, the Smalltalk flavor of Objective-C felt a bit alien to many, who had grown familiar with the C++ flavor.
