"Antstream Arcade is now available on the Xbox Store for $29.99, which will entitle you to one year’s access to the service. You can also pay $79.99 up front for a lifetime pass. If you want to test it out first, there’s a free tier available on the web."
This is completely anti-consumer. A few months ago Microsoft removed free applications similar (and better) than this from their store, only to then turn around and release a paid option because they want more of your money. I wish the developers of these applications had the financial backing required to pursue legal action to a result similar to the Apple v Epic Games lawsuit.
