It's SciShow's Video. Anyone can easily understand that. I just shared it through Dtude. I didn't upload it and claimed it as mine. It's not plagiarism. You are still viewing the video through YouTube. It's allowed for anyone to share any YouTube links through DTube. It's like sharing a YouTube video in Facebook. Now you tell me what is your problem ? Still If you didn't understood you can downvote all my posts. It's up to you. I don't care.
