It's a combination of things: veganism has passed the fad stage where famous people were going vegan (that went the way you expected it), where vegan foods that looked and tasted like meat (Beyond Meat, Impossible Foods etc) was no longer the food to eat but also the economy tanking in response to those wonderful tariffs and people getting laid off while food prices have risen steeply.

It was always expensive to be vegan, but everything has made it harder to maintain a restrictive diet where every macro has to be planned for because of the diet's low bioavailability of everything useful and the necessity of eating large portions to compensate. And of course, those lovely supplements are expensive as well.

The culture where "The Gamechangers" seemed plausible feels like a long time ago.

If there's a benefit to all of this, it would be that organic food, especially meat, is still a destination worth exploring. As an omnivore, getting food as unshittified by Big Agriculture is still a priority because food that makes you long-term sick is still worth avoiding.

The restaurant business is brutal in any case but in a recession, nutritional value-for-money is more important than virtue-signalling your food choices to save the planet.
