Based on nothing other than intuition, I assume the Stack Overflow audience still at least slightly selects for React developers over jQuery developers, compared to the general public. Of course, that doesn't really matter — we're talking about Stack Overflow users, and you're right that this is a way better source of data on what Stack Overflow users care about. Not sure why I didn't think to check their developer survey.
