It's easier for the EU, they don't have many MAX planes. It's likely too early to say something definitive and in times of social medial pressure one conformes if possible.
Norwegian by comparison have 18/163 - a far higher proportion (of course Norwegian isn’t an EU airlin but they have EU subsidiaries included in that total)
Norwegian is technically an EU airline because despite the name they're also headquartered in EU countries. This is so because being EU-based they're free to use all EU airports to base flights out of, which they use to good extent to make flights between the US and the French Caribbean islands, something that would be impossible had they been solely HQd in Norway :)
