Exactly what I am talking about along with the immortalized cell lines stolen from minorities. I have no problems with people donating themselves to science or being appropriately compensated with thoroughly informed consent, the advances to science are critical. I just don't want the biomedical equivalent of OpenAI stealing IP happening to make the 0.1% even richer.

Like Henrietta Lacks, who I mention in another reply, who had her cells harvested from a cervical cancer treatment and propagated indefinitely to be used as human medical specimens. Pharmaceutical companies have already attempted patenting portions of the human genome, so having them take sections of your personal genome if you have an allele mutation they find profitable is a concern. Using your genetic code like an advertising fingerprint to sell you treatments or services. Selling that data to third parties. Making registries of people with specific genetics for use by Governments to regulate or oppress, either eugenically or ethnically.

There are multiple movies where instead of growing individual organs they clone people for harvest, which I would hope is just too far beyond the pale to ever leave Hollywood but, then I remember shit like Unit 731 and Josef Mengele. That last one isn't really a real fear, but had to mention it.
