Brin's partner co-founded https://www.23andme.com/ and that got it's nose cut off by the FDA IIRC.
I'm in favor of protecting people from bad medcine, but I think the current regulatory structure is an overly-restrictive tool for the job. Either that, or (given that it steps on the neck of 23andme but lets GNC and homeopathic practitioners continue to operate) it's mis-tuned for modern technologies and tools.
