This isn’t a mark of degradation at all. “Back in the day” of non-monetization isn’t sustainable for any decent length of time because eventually the people donating (VCs) will want a return or will run out of money.
If they are raising prices (amount of ads shown) and people continue to pay then I can’t fault them for it.
As I type this I realize that both you and the person I was originally responding to are just expressing that you don’t like the price increases. Which is totally fair.
Of course they could, just make it part of the service agreement.
I would feel much inclined to pay for youtube if they filtered out all ad-funded content.
Even better, they could have a model where content creators for the paid service got their piece of the revenue based in quality metrics rather than quantity metrics.
And reddit has just turned into the same hundred jokes repeated over and over again with the same desperate-to-look-clever pun thread at the top.
