What’s missing is that Pixelfed shot up in usage this week with it’s official app releases on Apple and Google app stores. It at one point surpassed Facebook and Instagram in the top 10 on Apple I think. That surge was enough to reduce Mastodon’s usage to under 70%. I think Pixelfed monthly active users is now like twice that of Lemmy.
I’m on Android so I didn’t look into OP’s app. I just went looking into it after this post. Apparently if you create your own developer app ID and patch an app to use yours instead, I guess your usage is too low for Reddit to bill. Something like that.
