Haven’t bought name brand Pop-Tarts in years, but have occasionally picked up Toaster 'Betes or whatever the off-brand versions are called.
Noticed a ‘sale’ on the name brand and got conned into buying them. They’re now smaller, have less frosting, and have way less filling. The damn things were so flimsy that two of them snapped trying to take them out of the toaster.
If you get a craving for some nice sugary betes for breakfast, stick to the off-brands. They’re now higher quality than the name brand.
The future is stupid.
That’s not exactly true.
Yes, most of it is manufactured by a co-packer. And these co-packers also make similar products for other brands. But each one (usually) has their own recipe. Sometimes the differences are very minor, others can be drastic. Sometimes they have specialty ingredients (e.g. Himalayan sea salt instead of regular salt, or a partner brand). Sometimes the co-packer offers a standard recipe as a starter for the smaller brands.
Historically, the brand-name used a higher-quality recipe, worthy of the higher sale price. Generics would use something cheaper, comfortably taking the lower end of the market. Costco’s Kirkland brand is famous for going a step higher than the major brand, which is very unusual for a house brand.
Anecdotal, but it was true for the company I worked for. Used to make ten brands of sump hose - the only difference was the bag we put it in and which fittings were included. The material, molds, and specs never varied.
