The Aurora Store, alas, will never be a sustainable solution to the problem of proprietary Android apps. It’s always going to be a clever hack that survives at the pleasure of the big corporate gatekeeper.

Getting apps via random APKs on the web is even less of a solution, and a terrible idea if you care about your security.

As things stand, web apps and PWAs are the closest thing to a sustainable solution if you need to access corporate services (but there aren’t enough of them and banks will never offer them). For the rest, use F-Droid or somehow get the apps direct from the developer, via Obtainium or similar.
