I don't have a problem yet because it's not that intrusive, but in general I despise advertising. I think people are just thinking about the future when nostr becomes a larger audience and advertisers see a big opportunity to reach people and what that could look like. What if there were 50 zapvertisements on a popular post and you wanted to see who had zapped not for advertising? You would still have to look through the ads even though you didn't get zapped directly.
