Google allows sideloading of apps. Of course if you start on the play store and get kicked off that can kill your business, but if you build your audience elsewhere it can work out just fine. There's a pornhub Android app, and an ecosystem of dating sims, visual novels containing erotic content, etc. Patreon is probably responsible for a couple of million dollars a month in Android app "subscriptions".

This is probably only viable when your entire category of business is forbidden by the two big app stores. That is to say, it's possible to survive as "the big porn service", but not as "the mainstream social network that doesn't ban porn" (unless you're Twitter/Reddit and you're too big to ban).
