Ads for a paid service. nice.
Go buy a paper copy of a magazine or newspaper, or subscribe to one. Does your 'paid copy' have ads in it? It does? Why do you suppose that is? Is it unmitigated greed, or could it be that your purchase price alone isn't enough to cover the costs of generating the content within?
The last several decades of internet content distribution has had the unfortunate effect of training people to think that there are few or no costs involved in creating music, the written word, film or television.
There's a reason that there's now very little news coverage of your local and state government, and that national news coverage is dominated by talking heads, skewed opinions and hot takes. Nobody wants to pay for thorough, sober journalism. The business model for national news relies too heavily on drama and outrage to attract readers and viewers. Apparently that business model doesn't scale down well enough to work in smaller markets.
So sure, individual publications or newsstand aggregations like Apple News+ could probably offer a paid, ad-free tier, but you wouldn't like the price.
That said, there's a balance to be found, and I absolutely wish more ad departments would lean into a model that really touts the quality of the content as the draw, and then pushes the idea that fewer ads increase the effectiveness of actually reaching the audience and is worth paying a higher rate to get that more exclusive spot.
