I think this would be a better argument if Apple wasn't so careless with what they accept on the App Store. There are scam apps, apps which try to trick users into accepting subscriptions, tonnes and tonnes of "casino for children" games, games which clearly try to trick children into spending their parents' money, etc.
If you think "app store spam" is a real thing, you've spent way too much time on app store.
I install apps that I need -- news, banking, podcast, email, Uber etc, usually from well known companies. A small amount of apps are lesser known but they have good reviews.
I don't think there is any fundamental difference from the Apple app store. Maybe do a check of yourself first.
