It does not necessarily imply it. But if you'd know some more about
it you might understand that it's the natural way of thinking when
simulating systems' objects, and modeling object structures. Simula
in a natural way provided the platform to program object oriented.
(As said, without coining the term or speaking about "OO".)

Of course the ideas were there before Simula was released in 1967;
the inventors (also publicly) presented their ideas five years ago.

Yes, the Simula "OO" pioneers didn't invent the *term* "OO", but they
were (amongst) the first who spread the ideas and the first inventing
a language to model OO and work with the OO concepts that are still
used and implemented in many other OO languages nowadays.

(All the rest is [IMO] no more than dogmatic or marketing.)

If you have some substance on the topic I'm always interested to hear.
