> If the EU repeals Article 6 of the Copyright Directive, some smart geeks in Finland could reverse-engineer Apple's bootloaders and make a hardware dongle that jailbreaks phones so that they can use alternative app stores

Apple could easily block this, and in the situation described here of a complete rupture with the US, they would no longer operate and sell phones in the EU. If Google decided to do the same, that essentially leaves Europeans without smartphones. Microsoft could "brick" the rest of the EU's digital infrastructure overnight if they so wished, or were compelled to do so.

This makes the transition described in the article much more difficult. Although likely more urgent, from an European perspective.
