Probably pays for botted positive reviews. AddOn apparently can not download many different YouTube vids (not even music videos but plain, FREE content), provides lame excuses and then claims that they CAN be downloaded with a PAID version. Funny enough, the same "undownloadable" vids only available with the paid version of this scam can be easily downloaded with other (free) addons. This one should be removed or at least forced to carry a huge CLICKBAIT warning.
