They might not produce anything, but on the flip side they also are the only ones on that list that have to be prepared to increase data storage by hundreds of hours per minute! And that doesn’t include multiple copies for different quality etc.
Honestly YouTube is probably one of the few companies that deserves to be able to raise their prices unless they start deleting old content en masse so they don’t have to infinitely scale.
That being said, I wouldn’t pay $14. It’s just taking advantage of matching all the other streaming services raising their prices, something being done purely out of greed in the name of profits. Everything is overpriced now, I hate this.
