A fair questions fairly asked. I mostly use 1st party apps. I don't play games on my phone. I download my banking apps and apps like ecobee to control my thermostat (although I wish I could connect it to home kit without using the ecobee app), banking apps etc are from the store, I use MS Office which I pay for outside of the App Store and use the App Store to download. I don't do Facebook et al. All the apps on my phone fit on one screen with a few folders. I don't have hundreds of apps, perhaps 40.
I find the App Store useful for downloading apps for services I have purchased elsewhere (banking, insurance, utilities, entertainment), I have only one paid app from the store, AdGuard.
The App Store has its uses. I would never shop it like a store, I don't look at it as a place to find and buy products, but the place where the people I have bought products from distribute software to connect with them.
The App Store has a use case for me, but 99.99% of the stuff on offer it pure unadulterated, worthless, crap.
