I tried to analyze these two sentences.
Did I do right?

1. He (S) hates (V) people (O) keeping him waiting( present participle modifying ‘people’).

2. Steve (S) hates (V) being kept waiting (O = gerund phrase).

1. He (S) hates (V) people (O) keeping him waiting( present participle modifying ‘people’).

2. Steve (S) hates (V) being kept waiting (O = gerund phrase).

Yes, both are correct. Both objects are direct objects answering the question what?

And the present participle is modifying people, as you said; it can also be seen as a reduced relative clause: “...people who keep him waiting”

Thank you.

Thank you.
