| > Your free to not use 23andMe if you don't consent That is not how consent works. If I am selling you an apple, but thereby you give me consent to use its genetics for research, and without that we do not do business, then there is nothing optional about it; no opt-in, no opt-out. Opt-in is when the flag is disabled by default, and you can enable it if you want to, and use the product regardless of your choice. Opt-out is when the flag is enabled by default, and you can disable it if you want to, and use the product regardless of your choice. |
Opt-in is when I buy your apple.
Opt-out is when I don't buy your apple.
