That’s just one solution/ Company they banned. Not really anything to write home about from Unity’s perspective (although a big deal regarding the middleware developer).
It’s a ban to that specific middleware after they were in violation of an EULA.
This is the middleware’s company fault. They built a solution in violation of EULA and failed to comply for more than a year after notification. Note that the EULA requires an special license, it’s not a ban (PSNow and other streaming services are authorized).
Cloud based middleware offers affordable solutions for projects with limited budget, but it’s always scary to base the foundations of a project on a service you don’t own and can’t guarantee will work in the future.
