Historically there have always been ads in paid news media (look at the newspapers, they have had ads in print since almost their inception) so I don’t think there is anything out of the ordinary here…
I.e. for paid print media the ‘correct’ amount of ads is almost definitely non-zero from the publishers perspective.
(Personally I’m not too bothered about ads in a paid online website as long as they aren’t excessive or intrusive but people may disagree and can vote with their wallets)
