Several campaigns have moved away from Illusion of Choice portrayed in games like Storm Kings Thunder, Or Hoard of the Dragon. While some like Descent unfortunately propagate it.
Choice within agreed parameters is not the same as Illusion or Choice where nothing the players do matters. Beginning with the premise that the characters want to tackle a particular disaster, or find out why demons are roaming the underdark, or work out why IWD is undergoing nuclear winter is not railroading when it is agreed in advance. Any more than a writer setting their campaign in their homebrew setting is railroading characters because it isn’t a Wild West setting.
Tomb of Annihilation, Rime of the Frost Maiden, Curse of Strahd, Out of the Abyss, DotMM, Dragon Heist. All allow for wildly different journeys and outcomes. It’s a bit frustrating to hear you refer to products inaccurately or lump them in one box. I get that they are not your cup to tea so you don’t read them. Perhaps don’t dismiss them so lightly then. I have no issue with people choosing to play other styles: story-now, or total home brewed sandbox. Campaigns with a plot are not better or worse, they’re just a different flavor of spaghetti sauce.
Your claim that these adventures aren’t complex or involve choice is ill informed. Buy smooth or not. It’s your choice, just don’t make unfounded statements about chunky.
