Cheers!

I disagree with one of your statements – that “…the information presented belongs to the speaker.” The presentation itself (e.g., the Powerpoint) – yes. The handout or syllabus – yes. The information presented – not exactly.

If I take notes about the content, or just remember what was said, and write about it in my own words, then that does not belong to the presenter. It’s my interpretation. It may be right or wrong, but it’s mine.

Did you know that you can put copyrighted material in a presentation, as long as it’s not “published” – on paper or online. Good practice is to credit the author, of course!
