So you buy premium - now you don't have ads from YouTube anymore. But now YouTubers such as LinusTechTips and who else not want monthly payments for their exclusive content. Yea, that's not going to work. Now your watchers don't watch your content.
.. or a competitor (who's a competitor to LTT? GamerNexus? MKBHD?) would take their place.
LTT does have some interesting videos, but yeah, most of their output is full of ads.
