using YouTube on your website do show related videos when the videos end, and those related videos are your competitors videos which will be displaying on your website.
Most YouTube plugins like YotuWP, do allows you to turn off related videos.
Using gamipress YouTube, doesn’t have that option.
So in future upgrade as you said, if there could be that option to turn off related videos, or any integration with YotuWP plugin.
That will be great.
