My problem is I paid $10 for Android and $10 for Windows in the past. Now, with version 6, the $10 lifetime license I purchased for Windows will no longer work with the Android version. They broke the product I purchased. So, honestly, this would be a *second* payment of $10 for an application from the Windows store. You can't guarantee its a *one* time payment since this is already untrue. If you're willing to give money to people simply because they ask you for it and haven't earned it, that's your own problem, but it doesn't mean you can lecture other people about how they should give out money for free.
