I haven't seen any direct evidence of a premeditated conspiracy. Murray has, however, unilaterally mandated a rule change that favors Oracle. It was done in the name of "safety", but is really a performance tweak. People suspect collusion because Oracle publicly sides 100% with Murray against the other teams. At the very least, Oracle has condoned a subversion of the rules simply because the change benefits them
You're forgetting Artemis here. They're in favor of the new rules as well. That seems to imply that the Challenger of Record and the defender agree on the rules changes, and the other "and also" teams seem to have big problems with it for whatever reason.
