If you're sticking to the corporate shlock that's promoted on the front "explore" page of every podcast app, sure. If you stick to smaller podcasts that are patreon-backed or have a couple 1-minute ad breaks in the entire 90 minute show, it's fine. I mostly listen to comedy podcasts anyway and they tend to make ad reads entertaining by riffing on them. If it's just someone reading from a script, I'd skip it.
