Yeah, I thought it was a nice compromise. It seemed sensible that if Premium is the 'compliant' response to not wanting ads, the 'compliant' response to using third party tools to download videos was to just be able to do things more easily and with more options through Premium as well. But apparently they wanted to advertise something anyone who's wanted to download a youtube video would not describe as 'downloading', which is easily out competed by free (but at times shady) tools.
