The negative comments against genetic screening here seems to be 100% from people who either have no serious genetic diseases lurking in their family tree or are lying to themselves and pretending they don't.
I know that they went out of their way to a company that does not store genetic info for their sequencing.
In talking with them, they are also very against any form of this screening. The risks of the disease are very bad, but they feel on a population level that the risks of abuse by insurances or governments are much higher, per what they have told me.
