Brother I also don't like to get rewards from others content or work
Butt there are many videos on top social media platforms and original owner of content have no problem and allow others to use it for any legal or ethical purpose
If someone want to share this content on steem blockchain or any other dapp with proper source I think it should not be flagged by group on discord and steemit just for getting some rewards by downvoting ,we should leave it's up to community and users to decide whether they give upvotes and downvotes
I am trying to explain this problem there are some groups on steemit and discord if there leader downvoted on any post they all downvoted it
I personally use all original content I created myself.
If I do use a graphic or something, I'll always give source and credit.
