@hazelnot you give consent when you publicly post something online. In fact, guess what, I can see your profile and whatever you publicly post without even logging in to your instance. How? I use a web browser.
Did you also give your consent to an obscure 3rd party app to display your content inside it? No. Let's just ban them all then, just like Xitter and Reddshit did, or like Meta/Faceshit did in the 1st place.
Oh, it's so great when we have stuff to help us reach content, from friends, from people we follow, but God forbid someone else reaches our content from other parts of the internet. Those that want that are just techbros.
