People do this all the time in hobby groups and other social formations.

Right now in cycling the industry is pushing a new wheel size, and people are freaking out about it and saying they will ostracize people who buy a new bike with the new wheels. And every youtuber influencer is like making videos about how they will stay loyal to the old size… and they all did this over a decade ago and in a few years they will all be huge proponents of the new wheels once they are socially acceptable to do so.
