If you watch 10 hours of Netflix a week, you're watching about 3 and 1/2 hours of ads a month. All to save $3. Not to mention having access to less content.
I mean, across a 4 year college education, saving $3/mo is saving $144. That's like half the price of a cheap laptop or medium-priced cell phone. And when you have Spotify and whatever else, subscriptions add up. So it seems entirely reasonable to me.
