I misspoke in my first comment. It’s vague on if copyrights are shared but it does explicitly say it gains ownership.
In any case, this issue has been brought up and they haven’t fixed it. Every other platforms makes it very clear who has ownership of what. There’s too much room for abuse and its either a grift or incompetence and with all the other problems with the platform, it’s not a good look.
Federated platforms are popping up for this kind of thing, better to wait imo.
I used to do this constantly but I had to break myself out of the habit. On long drives, I’d forget I would have passengers and blurt out half a sentence before realizing.
It also led my step mother to try and convince my dad I was schizophrenic at the time since I would do it in the house as well when I thought no one was around.
Mildly annoying since it was just an easy way to think things through, I never saw it as a bad habit.
