There's a fine line between pentesting education and "how to break into a computer", and it's sad that instructional videos are now being banned due to this policy.
Is there a line? I fail to see any difference. I also don't understand how a video teaching how to make your software more secure is different from a video teaching how to exploit insecure software. For all I know, they are the exact same video.
If you teach "how to hack your own system, that you own", that's a different thing entirely.
Two different videos.
