I would suspect this too but I know it's not the case. I've been writing my own LLM from the ground up (literally from random weights, not from any other models) and have been training it on publicly available data and even my highly inaccurate model is able to maintain coherence that Bard completely lacks. For example: Bard just seems to go on a completely unrelated tangent and throw map directions at me for no reason. Given that I'm just one person, how is it that I'm able to nudge my model to do anything useful and Bard has remained stagnant for the better half of a year? It makes me suspect they're up to something bigger :P
