I'm not too worried about it because it's never a 100% overlap. Even my brother and I share only ~50% DNA. It gets way sparser for more distant relatives.
About insurance companies, they're legally forbidden to use such data.
Great training set to check the results of other factors, then use those to infer.
Moreover "legally forbidden" means jack faeces unless you can point to people who had convictions recorded and went to jail. Otherwise we're merely discussing business conditions & expenses.
This is completely false. Any two random humans have more than 99% overlap by virtue of being the same species. It's even higher for brothers. We also share around 90% DNA with cats, dogs and elephants.

This doesn't make sense. If they were equal, you'd be the same person except for environmental differences. Many applications don't need equal DNAs. E.g.

This is a very weak argument. There's a long history of companies doing illegal things, and even if it's illegal today it doesn't mean it'll be illegal tomorrow.
