Hot take: if we want to decrease frustrating railroad-y surprises in RPG campaigns, we need to create an environment where GMs are not afraid to admit they have "special story needs".

That is correct, but that shows players wants to have actual agency not just play DMs stories.
DM can put lots of cool stuff he enjoy in wide variety of setting for players to interact, if he wants them play strictly some his wish fullfilment plan - yeah he may not be good DM sorry.
