For apps that let you subscribe either in the app or on the web, do you voluntarily choose to pay 20~30% more for that convenience? For example, Dropbox is $12 in-app vs $10 on the web. Youtube Premium is $16 in-app vs $12 on the web. Spotify is $13 in-app vs $10 on the web. Do you think most consumers would choose to pay 20~30% more for that convenience if they were informed of that choice? And isn't it anti-consumer to deny them this information?
