Amber isn't encouraging users to handle keys unsafely so there's less reason to expect betrayal from them
Discussion
How is Primal encouraging users to handle their keys unsafely.
Keep in mind that most people won't really be jumping between clients.
But if that is your point, I get it.
Most of "their" users.
They are targeting newbies who don't want to think.
By having new users sign up without telling them about Amber, they increase the chances of new users investing time in an npub they created less securely than ideal, so they lose some of their early progress or get less benefit from Amber when they find out about it later
