CBDC is the worst possible option. This is the fastest way to dystopia having your money expire, getting fined directly from your account for things like JWalking, Etc.
If "Show security notifications" is enabled in security settings then they'd get caught, so I don't think Facebook is going to start doing that. The address book and metadata they have access to are more useful to them anyway.
except for all the false positives. every time someone gets a new phone in a group chat, someone has to ask "did you change your phone or is someone snooping at you", which creeps them out, because it's off by default, and so we ask less and ignore it, "probably changed their phone".
it's terrible ux for security, it could have been much more transparent and actually encouraging proper security behaviour.
Wut? MailDrop is what you're talking about and it's optional on top of only kicking in with attachments over 25mb IIRC.
Maybe you prefer whalemail, yousendit, or one of the other sign-up-free and get-ads-forever services for large attachments, and that's fine, they're not going away.
Neither is DropBox, for the time being. I'm both worried and excited about DropBox's new offerings and I'm all for it as long as they don't become Evernote and start selling backpacks and rebranded Fujitsu scanners. :(
tl;dr: I really don't like RN and wasted a ton of time trying to talk people out of it for mostly unfounded reasons that won't affect 99% of users in any meaningful way.
