If I was worried I wouldn't have furnished my DNA to a corporation with very little accountability in the first place.

I got enough out of the deal (instead of nothing from the government) that it was in my mind an acceptable tradeoff. No one's about to start cloning me.

Your DNA is not secret. You leave it everywhere you go. You have no reasonable expectation of privacy for your litter when you litter. It's only a matter of time and of tech before everybody has a copy of everybody's DNA.
