I think it comes down to how often you use the platform. YouTube has been my primary media source for the last twelve years and ads are what paid for that. Now that I can pay $14 (USD) per month to give the people I watch a bit more, have no ads, downloads, and a few other nice little features, it was a no brainer for me. I have always gotten _way_ more mileage out of YouTube than HBO or Netflix.

But if you don't, then it's probably not worth it and having an advertisement will pay for it instead.
