Two or three years, I think. So far the price has stayed exactly the same, they still have no ads, and they haven’t made any changes to the app to try to advertise features or anything like that. It was (and still is) a nice change from Spotify, Apple Music, and even YouTube to be honest.
Fellow former conservative christian here, and I share that pain. I eventually came around thanks to a LOT of patience from friends who understood my background.
I try to pay it forward by putting myself out there and extending a hand to anyone looking to understand and accept others. I have had decent success with anyone who asks in good faith.
