ESPN Radio 4.0 iOS Upgrade

ESPN Radio has updated their iOS app to 4.0 and it now requires a $4.99 payment to keep listening (on top of having to have an login).  I purchased the app a few years back for $2.99, so I understand why they are charging again.  I don’t use it often enough to pay for it, so it got deleted.  We are seeing more developers (even large ones) having to come up with ways to sustain revenue to keep working on their apps.
