Difficult to find a Morgan Freeman sound-a-like if they're not marketing themselves as a Morgan Freeman sound-a-like. And if they are (and obtaining more customers as a result), it's easier to pay Morgan Freeman royalties than come up with persuasive arguments that selling 'voiceovers that sound like Morgan Freeman' isn't profiting from deliberately invoking his likeness...

How about this scenario: they publish a youtube video, then someone says in the comments: hey you sound just like morgan freeman, then the company looking for the voice performance googles for morgan freeman, finds the comment and contacts them.

So then in court the google for Morgan Freeman and the comment you sound like Morgan Freeman come out and then you owe Morgan Freeman $$$$$$$$$ because he had to go to court over it.

Think if I wanted to earn a living as a voiceover artist who happened to sound like a very famous actor I'd rather advertise my USP and pay royalties on the much higher earnings than only pick up business from companies that make hiring decisions based on random chance or YouTube comments ...
