Okay, I had to go back and re-read the EULA carefully with my Tin Foil hat on.
I'm assuming your refering to this,
"(b) except as expressly permitted by this EULA and to the extent expressly permitted by applicable law, to rent, lease, sub-license, loan, exploit for profit or gain, copy, modify, adapt, merge, translate, reverse engineer, decompile, disassemble or create derivative works based on the whole or any part of the Game or use, reproduce, distribute, translate, broadcast, publicly perform, store in a retrieval system or otherwise deal in the Game or any part thereof in any way;"
This is a non issue and you must know it, I highlighted the pertant bit it for you.
"(b) except as expressly permitted by this EULA and to the extent expressly permitted by applicable law"
Live and recorded steams would be expressly covered by the local jurisdictions fair Use laws, which generally allow the use of an unmodified work for the express purposes of public and private commentary regardless if that commentary is sold commercially.
Well at least in the civilised world like the UK and EU, I’ve no idea how this would fly in the US, but given frontiers active support and participation with the streaming community they would are almost certainly support such actions.
Now if the streamer replaced all the spaceships with hamburgers, that then becomes a derivate work, and thus falls under this clause. (Though in that particular example would be covered by laws protecting parody and satire common in democratic legal systems.)
