The writing was on the wall for these new genetic studies the moment David Reich at Harvard discovered that a) the Indo-European "invasions" really happened and b) that Europeans, north, south, east and west, all share the same basic genetic admixture, making them a distinct people at the biological level. It's been a desperate rearguard action by activist academics, especially in absurdly colonised disciplines like archaeology, but the providers of access to genetic material and samples are now also doing their best to restrict access to the basic materials themselves, citing worries about "misuse" and "feeding into far-right narratives." It's pathetic, but it's also extremely pernicious, and the intention is very deliberately one of cultural and historical erasure.
