I don't think it's odd because there is now a direct conflict between Uber's future direction (autonomous cars for hire) and Google X's self driving car project. Regardless of any claims about a possible Chinese wall between Google Ventures (GV) and other Alphabet divisions, Uber is right to limit information access to direct competitors even if they are investors/advisors.
