Do you remember what youtube was like 10 years ago, or even 5? You might have a single square advert somewhere on the page at the top of the recommended to watch next videos. Then they introduced a single short ad at the start or end of the video. Now there's ads everywhere on the page, at the start, end, and throughout the video. It's naked greed.
What if next your 12 quid a month only removes the adverts on the page, but then they release a higher 20 quid tier to remove the ads in the video? See netflix subscription -> multi screen tier -> 4K tier. These companies want to squeeze every penny they can out of you.
And if £12 a month is such a good deal, why is everyone here using a Ukraine VPN to pay less. Because clearly they don't think it's good value for money or fair to pay £12/mo just to remove ads that have been forced down their throat.
