I don't know why this is such a shock to people reading HN. EULAs have always granted a license to use typically on a single computer. They have never granted a license to own (would gladly be proven wrong if someone has an example). It's not your code. You can't own it. I'm sure they are concerned about having to support the legacy code. Yes, converting to 100% subscription based users, but if they can pull the plug on any responsibility to support old code, that would be ideal for them.
