If Google did indeed offer to continue under the current terms, then I would say that Roku seemingly is the one that is at fault. If Roku is trying to renegotiate other items under different terms, it seems reasonable for Google to be able to ask for things they want as well. For example, if Roku wants a bigger cut of ad revenue, it seems reasonable for Google to come back and ask for silicon supporting AV1 to be installed on future Roku devices. (I have no idea if that is the source of contention, but I'm just saying it seems like reasonable, good faith negotiation.)
