Between the demand to install an app we are prohibited from even "decipher"ing and the theft of content, I don't think this service is anything I want to be a part of. I thought they were trying to be something better.
The contract language that informed my opinion follows.
When you post Contributions, you grant us a license (including use of your name, trademarks, and logos): By posting any Contributions, you grant us an unrestricted, unlimited, irrevocable, perpetual, non-exclusive, transferable, royalty-free, fully-paid, worldwide right, and license to: use, copy, reproduce, distribute, sell, resell, publish, broadcast, retitle, store, publicly perform, publicly display, reformat, translate, excerpt (in whole or in part), and exploit your Contributions (including, without limitation, your image, name, and voice) for any purpose, commercial, advertising, or otherwise, to prepare derivative works of, or incorporate into other works, your Contributions, and to sublicense the licenses granted in this section.
As a user of the Services, you agree not to: Except as permitted by applicable law, decipher, decompile, disassemble, or reverse engineer any of the software comprising or in any way making up a part of the Services.
I think you're right, but this is usually a developer skill issue. This UE developer thread was really useful in understanding the 'why' of ugly motion blur for me. https://forums.unrealengine.com/t/correct-motion-blur-values-to-use/131392
