As ubiquitous as the phrase “hit the subscribe button” is on YouTube (it is the number 2 trafficked site globally) I really have a hard time believing that telling someone to subscribe to your podcast makes them think they have to pay. Edison offering a “you have to pay to subscribe” option in their survey is a bit of a leading question if you ask me. I don’t think anyone under 50 confuses what “subscribe” means in podcasting.
