Browsers suppressing ads by default leads to the question of what counts as an ad. Borderline cases: sponsored portions of YouTube videos (a la SponsorBlock), videos containing entirely sponsored content, movie trailers, game/software demos, freemium games, free credits for cloud services, product placement, soliciting Patreon subscriptions, sections calling out or listing names of Patreon subscribers, publicly thanking large donors (charities do this), things with ads in the name (e.g. sports arenas and events), things named after donors (e.g. college buildings), soliciting subscriptions to their own subscription service (e.g. Linus Tech Tips YouTube videos promoting Floatplane), soliciting subscriptions to a partnered subscription service (e.g. many youtubers promoting Nebula).
