If I had to guess, I'd say that Apple and Google probably have a contract that covers how this transfer takes place, and it takes some amount of effort from their legal teams to ensure that it's a valid contract that complies with the laws of each jurisdiction. As a result, they started with the highest-value jurisdictions like the US and EU first. Regarding Liechtenstein, it is (along with Iceland, Norway, and Switzerland) part of the European Single Market [1] via trade agreements with the EU, so it's possible that it was trivial to adapt whatever contract they were using in the EU to cover them as well. I don't think it's a coincidence that all 4 are on the list -- but again, this is just a guess.
