No facebook doesn't do that, but someday they might, YouTube does and other sites do. Not sure I see your point just by naming other social media who do or don't do similar...? Instead of using that logic, show me where the rules here on Hive say you can't share people's content?

So... Hive/steemit has rules against just regularly sharing content even when someone like my friend is giving attribution or openly stating she doesn't own the rights? Is that right?

I've been here as you said for a while and have seen tons of people doing similar and having no problems. I've personally done similar many times, I just shared a meme the other day and no one said anything. I've studied copyright law and my understanding is that people can generally share to their personal blogs or social media pages via fair use as long as they aren't claiming the content is theirs.

I would suggest that you don't suggest I'm being dishonest or pretending ignorance because you're not telepathically in my mind and to infer such qualities when I clearly don't possess them is dishonest itself and inaccurate at best and slanderous on the other end of the spectrum.
