IT IS NOT OPEN SOURCE - though you do get read access to the source code. You&#x27;re right that you aren&#x27;t forced to use their services, but you are also NOT permitted to use other cloud providers. So, it&#x27;s either AWS or your own hardware. Still, this does seem rather amazing. One thing you left out is that there are no revenue sharing requirements either. You&#x27;re not even required to use this for game development - you can use it to build movies, training simulations etc.
