H-h-how? HOW? do they ‘anonymize’ DNA?!?!

If you really curious, it is possible depending on the sections of the DNA being shared and how aggregated they are. Not saying that this will be the case - it’s quite likely that this sale would be done prioritizing value instead of privacy - but it is possible. The key part is to not treat the whole DNA as a data sample, but specific sequence sections, as isolated as possible.

And the Netflix example is instructive but not super relevant here. If you already have your SNPs in a public database out there, then yeah 23andMe might not be able to effectively anonymize your samples; but you don’t (I hope).

We don’t prove negatives in science

That’s simply not true as a general statement lol it very much depends on the negative in question, or what you define as a negative
