What are you paying for when the price is going up 10-25% a year? Are you watching 10-25% more? No, beccause the price of YTP isn't anchored in any kind of economic reality, as 95% are watching the free version with ads or adblock. That ad revenue is what drives their strategy.
YTP is essentially a protection racket. Pay up, or the ads can get a lot worse.
Not sure about you but I got options for higher bitrate streams this year and honestly for the sheer amount of content available it is still significantly cheaper than other media I pay for.
There is a point it will stop making sense to pay for YouTube but at the current prices it isn't there, if it gets there then there will be a different conversation to be had.
The issue I see with people who are able to pay but wont pay is that Google will decide it isn't worth the overhead and we end up back with ads only and significantly more aggressive adblocker prevention mechanisms.
If you watch any significant amount of content pay for it, if you don't then an ad or two really shouldn't be an issue but then likely neither is your adblocker usage so go for it.
