For example, on calls with customers/partners, or with a recruiter, or for a job interview.
Thanks, fellow human. You probably just sold out my voice and likeness -- and, if I don't notice and disconnect immediately, the content of our conversation, and any info I might share -- to some ruthless sociopath techbro startup. Which will use and abuse and leak the data. Even though they don't have rights. And it's actually a felony to be recording calls without consent where I live.
