You Can't Look at Porn on Any Reddit Third-Party App Now

This is a most excellent place for technology news and articles.
The Apollo dev said $2.50 a month per user. Not that bad really if reddit had given developers enough time to change their apps and the sign-up process. He got screwed by already having an existing Premium that people had pre-paid too.
It's $2-3/month, but that's assuming all your existing users convert to paid subscriptions.
The issue devs had was that it was going to mostly be the heaviest users who would be willing to pay for a subscription. The people who spend many hours per day using the app and rack up $20/month in API charges.
Yeah, they would have to include some limits so a user wasn't costing the app developer money. Not all existing users would have to sign up, though - people would just have to be required to sign up and pay to use the app in the future. It's certainly quite a disadvantage for 3rd party app users have to pay while the official app is free.
