I believe people's image or likeness, including their voice, is protected from unlicensed and unauthorised use, this is specifically intended to prevent people from implying celebrities endorse products and such. Though I'm sure there are some extensions to that which would protect against political speech and maybe even deepfakes. That being said, if the person actually said the things they said, in a prank situation, it may not be covered by those laws, as it would be a natural and honest reaction from them.

You imply I should taint the sanctity of my device with the abomination that is Twitch?

The ACCC (Australian Competition and Consumer Commission) is suing Google for breaching Australian privacy laws in regards to data collection and dissemination. https://www.abc.net.au/news/2019-10-29/google-faces-accc-federal-court-misleading-use-of-data/11649356

After a recent ACCC investigation into customer complaints stemming from "error 53" messages they received after an iOS update, Apple had a $9 million fine handed down a Federal Court. This after Apple admitted to misleading at least 275 customers as to their eligibility for repair. According to the ACCC The court found that the company did not have the right to deny service even if the customer had the device previously repaired by a third party. Further, the ACCC Commissioner clearly pointed out that if the device is faulty and the customer would like a new device or a full refund, they are entitled to demand such from Apple rather than a refurbished device. http://www.abc.net.au/news/2018-06-19/apple-fined-$9-million-for-misleading-customers/9885244
