How is this very post licensed and how would you know? Do #Mastodon instances dictate a #license on users posts? Is there a way for me, the #author, to assign one and pass the information through the #fediverse? Do I give away my #copyright in the moment, I press on "Publish!" below? (Or press C-c C-c in #Emacs#mastodonEl?) Can I limit #distribution e.g. to notforprofit entities? (Not that I wanted to. At least not now.)
