One could argue that from an effectivity viewpoint (helping as many animals as possible), veganism is not behavior-focused enough. Within (strict) veganism, it is better to never eat any meat and dairy and do nothing else than to sometimes eat dairy and donate $10.000 to effective AW charities. In this case, it is better to shift behavior, but veganism is too belief-focused.

I also wonder whether this discussion distracts from what is really important. Most vegans I know in real life (including myself) are somewhere between 95% and 99.5% vegan, and do not push each other to increase that percentage further, since there are more impactful things to focus on. In other words: there are circles in which veganism is already loosely defined. I don't know how common this is though.

I am surprised to see how wildly the outcomes of these approaches vary. According to your napkin approach, such a video is not worth more than $60 (or in other words: if it is more expensive, there are more effective approaches). That seems hardly a worthwhile endeavor to pursue.
