It's illusion that owners in Lithuania (or as they say, "Switzerland") would refuse to collaborate, lose everything they have, and accept to go to jail for you to protect one person storing pictures of kids, or someone planning a terrorist attack.
Though now with this Gemini scanning all the emails, Google can now reliably flag content at scale "to protect children / fight terrorists / flag illegal content".
Before, they had to do broad keyword match and this ancient picture database matching.
In Switzerland, law enforcement can't just ask for data without a court order. And companies don't give it willingly, either.
