An involved alternative is to access whatsapp through a matrix bridge. It requires either paying for hosting or figuring out how to host a matrix server and the whatsapp bridge [1]; I do the latter and can attest it's not very hard if you have a technical background (and you're on hn, so you probably do), but YMMV. There's a lot of matrix clients, all of which open source; and the whatsapp bridge works really well nowadays, enough that I've been using it almost exclusively for my texting (no whatsapp calls tho).

In fact, I recently bought a non-smartphone running KaiOS, and use whatsapp through a matrix client, chooj - which, although in early alpha, works well for my use case of accessing whatsapp while outside the home without having to carry an addictive smartphone with me. KaiOS does have a native whatsapp app, but it does not support whatsapp web at all, and that is an absolute necessity for me, especially when typing requires (bad) T9.

My point is, matrix bridges afford A LOT of freedom with how to access whatsapp (and other closed-source communication apps), if you're willing to deal with some friction. And now they're stable and mature enough that they work pretty darn well - no doubt thanks in part to support from beeper [2], which funds development for several major bridges. Within the android ecosystem, beeper is probably the easiest way to gateway all your communications through matrix, though I have no experience with it. Sounds like paid matrix+bridge hosting, plus a generally much nicer and frictionless experience.
