Beeper is maybe an alternative. It is basically a matrix bridge. But not only for WhatsApp, also for signal and iMessage and many more. (Now in Beta, later 10$ a month subscription) https://www.beeper.com
There’s nothing about Beeper that makes running WhatsApp through it more private. You’re still using the Meta platform, but you’re adding a new company in the chain. Your messages from the WhatsApp server get decrypted by Beeper then re-encrypted to be sent to you.

You can at least remove the aditional company by hosting the bridge yourself https://tube.jeena.net/w/rYhp4ZT5Ykw1aBGqMr62KG
But I don’t think OP was askiing for more private just for a alternative.
