My suggestion to the developer would be to offer the app to Pocketcasts for a fee based on his daily rate (to cover the time he took to wrote it) plus a reasonable royalty percentage per year. He could then have his app, not need to maintain it at his own cost and possibly make a bit of cash from the royalty. If the Pocketcast people give it away for free, he makes only the dev cost back - but doesn't lose much really - but he gains the app he wanted.
