Final answer:
To change the sentence 'He hates people criticizing him.' to passive voice, it becomes 'He hates being criticized by people.' This shifts the focus to the action of being criticized.
Step-by-step explanation:
The sentence 'He hates being criticized by people.' is the passive voice equivalent of the active voice sentence 'He hates people criticizing him.' In the passive construction, the focus is on the action of criticism rather than the doer (the people), which aligns with the rules of changing sentences from active to passive voice.
