As I understand it, you only share half of your DNA with your parents and siblings, even less with more distant relatives, and it’s not easy to tell which bits of DNA come from where. Also the records are anonymised so it’s even harder to figure out which person you can infer information about.

Well, for a geneticists it is „easy“. In this paper which is a little older they just look at the Y-Chromosome and the last name, something men share with their fathers, and public accessible data (at the time). The pedigree is resolvable. Link
Therefore it is important, that this data is access restricted. For this we have EGA
So using for profit services like MyHeritage is risky and stored on servers you might not want your data on.

Names are not included in the data set.

I am aware of this, but with little information it is possible to identify people. It was more about the: oh we share only half with our parents. Who can figure it out?
There is a good reason to keep this data access restricted. With little sensitive data, you are an open book.

It’s a good job this is restricted data, then. :)
