That's in no small part due to my being both able and willing to tell "social pressure" to go jump in a lake.But what all these forum and restaurant analogies miss, is that with RPGs your old books don't vanish and you can just keep playing that. Like I was not so keen on 5.5 changes, so we just kept playing 5.0.
I get that "current edition" matters for wargames where you ideally want a large pool of opponents, but with RPGs it is quite different. You need just handful of people who want to play the same game, and if you already had your existing group that liked the old edition, it should not be hard to just keep playing it if the new one is not to your liking.
Like @Lanefan my understanding is that you run some frankenpaleo-D&D, and that seems to have been going strong for quite a while.
I've never cared about being one of the cool kids. For many people, however, conformity, "fitting in", and following the latest trends is highly important; and marketers - given that it's their job - are very good at setting trends and reinforcing this behavior.
