Many Europeans are upset that Apple blames Europe that they cannot implement this because it would sacrifice privacy. (Which is kind of ironic, because the EU has nearly the best privacy protection worldwide.)
Apple doesn't care about privacy. By default (without ADP), your (i)Messages, Drive files, contacts, calendars, backups of data from third-party apps are not end-to-end encrypted [1]. US law enforcement can request it. EU citizens are not protected because the US can use the CLOUD Act to demand the data. If Apple really cared about privacy, they would have closed that hole long ago.
