I used to watch YouTube quite a lot on my TV without ad blocking, but over the past few years the quantity and duration of ads became so incredibly ridiculous that I stopped doing that. It's probably not what they intended, but the primary effect is that I drastically cut down on the amount of time I spend watching YT. Whenever I do watch videos it's now on desktop or mobile with an ad blocker, and it's not enough to justify the price of Premium.
