But it was a problem that peered from long ago, it was implicit in the plans (cpr. the "digital euro"), and if you do not secure what you need for your plans doubts are legitimately cast about you.

Edit: sorry, there is a possibility there is a case of bad communication. A comment nearby (https://news.ycombinator.com/item?id=50486125) mentions the open specs could allow for the non-requirement of Google, Apple and the likes. I may have leant on thinking that the situation could be similar to that of age verification - for which the EU built open software for ZKP, but it is said to require Google or Apple or the likes.
