They don't have to be, as far as I understand it. I've installed a few websites as apps on my phone (because their app had trackers in it) and they can work really well. Examples are Bluesky and Flipboard.
An example where I agree with you is LinkedIn - installed as a web app due to trackers - but they know this, and the whole point of their app is to get you with Facebook and Microsoft trackers, so they make the web app experience miserable on purpose.
