YouTube is the only platform that has sponsor block plugin which allows you skip all ads, self promotions etc.. Hard to compete with that.
But yeah, I'm fine with using the skip x seconds in my podcast app as well for now.
They are also dynamic based on geographic location from which you download, which results in drastically different ad loads based on where you live. This is probably one of the reasons that a sponsorblock-for-podcasts has not yet happened.
