The ideal would probably be what Steve envisioned before the AppStore was a thing and that's basically PWAs. But I think it's been alleged that Apple is arbitrarily nerfing Safari to prevent PWAs on iOS running as well as native applications -- though I've no source.
How to effectively "disrupt" the appstore model is a billion dollar question I'm not sure of. What I do know is that the Tim Sweeny's et al of the world are hypocrites in that they just want to create their own rent-seeking AppStores and charge their own commissions and skirt around paying the platform anything for being on the platform. This is akin to wanting to be in a supermarket and put your kiosk inside and sell your product to the supermarket's customers without some sort of financial agreement between you and the supermarket.
The courts don't take stuff like "social compliance" into account when evaluating something like the iPhone, so it all looks rosy. In reality, it's incredibly difficult to be a social young person in the US without an iPhone. Which naturally spreads to families becoming "iPhone families".
All of it just comes down to messaging though.
