Claiming that people donate anonymously because they are concerned about claims to their estate is, IMO, pretty ridiculous. There have been millions of sperm donations done through fertility clinics and not one documented case of any offspring laying claim to an estate.
You claim restriction on testing seems reasonable - restrictions for whom?
For the offspring? As another person pointed out, they have no agency in this. They did not sign a contract promising anonymity. They should have every right to seek out their genetic origins.
For your 3rd cousins who you've never met? If even one of your distant relatives has tested on one of these sites, it's incredibly easy for an offspring to track you down and figure out who you are.
How would you suggest restricting or preventing that? Whose usage would you restrict?
