that’s stealing
It’s important to note that copyright violation is never stealing or theft. That’s a poetic term copyright maximalists use to morally equate two disparate concepts. Stealing and theft involves taking something that is finite and rivalrous and thus depriving the owner of it.
Stealing a kiss is another poetic use of the term.

As an artist, I don’t. Plagiarism is about failure to cite sources and copying content while claiming it’s yours. That’s not even usually a legal issue. It’s an academic issue. And it’s not necessarily immoral either. You can be accused of plagiarizing yourself by not citing that you had previously written some of the content in a previous work. That’s not even close to stealing, technically, legally, or morally.
Plagiarism is also very different from copyright violation.
And it might get you fame and fortune and acclaim from others. Depends on the context.
