I think, most likely, you overestimated the consideration of the majority. I may be wrong, though. Most opinion I read or heard about are more emotional drived.

Doesn’t matter. In the reach of EU, some law about Chat Control. If they make this into law, no provider within the EU will have a choice in this matter.
