You see how Cheetah provided a link? That link is where this information was taken from. Cheetah is a bot that identifies when someone has copied material from another website and failed to provide that site as a reference in their post.

Copying and pasting material from other websites won't bring you success here. It will just get your posts flagged, and eventually Cheetah will put you on its backlist which is not something you want to experience.

You can write about any topic you want, and in all honesty you can plagiarise as much as you want as well. It all boils down to what you want your Steemit experience to be. Something positive or something not so positive?
