@2du @jonny This is my stance too, it should be opt-out, or opt-either, where it asks what you want when you sign up and you must pick an option to use Mastodon.
I suspect most people probably expect their posts to be automatically viewable (it is everywhere else!), and those that definitely don't want them to be know where to look.
@mattswift @jonny very good points. While I appreciate the concern for privacy.. this is social media. Posting to the internet isn’t private
