There is one problem. There are apostate videos on YouTube. Once you start watching videos from jokehovians in good standing, pretty soon the algorithm will start picking apostate videos for you. Watch one of those, and you are going to see the truth about this cancer of a religion. And before you know it, Brother Hounder will be talking to the whole congregation in front of 40 or 50 others, about how you got disfellowshipped following watching YouTube videos.
As for non-religious videos, it is possible to get into videos about politics. Whether it is about the mandatory torture shots, the economic hardships, why you should be buying silver and gold (or tools and food), or just watching nature without joke-hova, you will be getting into territory where the hounders can catch up to you. At least, they can get you for "brazen conduct" if they don't like you watching these videos.
And, it is all too easy to be listening to music videos such as Led Zeppelin. Before, you would have to go out and buy a CD or download a song. Now, it is as easy as typing "Led Zeppelin" into your YouTube search engine (at least it will be until Komodo Dragon Harris pulls the plug on it, at which point YouTube will be entirely Google content) and playing your videos without any subscriptions or fees. And, there is no way they are going to put up with that for long.
