Maybe write to Red and ask them if this means they have a right to your footage? Say that you will publish the response. Their reply could be no, yes or no/yes

Maybe write to Red and ask them if this means they have a right to your footage? Say that you will publish the response. Their reply could be no, yes or no/yes but... and their response will be usable in litigation, so they'll have to weigh the legal protection with the PR damage. If they just repeat the EULA then treat it as a yes, hammer their social media comparing it to Apple's, ARRI's, Panasonic's etc. stance and let the EFF warn everyone.
