But I also have to trust the server with my meta data if they open source it? Threema still has the advantage that they don’t need any personal information at all to create an account to the metadata can be as little as “key 1 send a message to key 2”
The metadata is who (IP address, so location) is contacting whom and how frequently they are doing so. Unless it’s P2P, which it doesn’t seem to be.
It’s an inherently flawed system due to its centralisation. Check out https://matrix.org for a fully free and open source software stack where you can host your own instance and control your own metadata.
ISPs are pretty cancerous, yeah. I mean even if you don’t host it yourself you’re susceptible to whoever you get to host your server and their ISP. You could use a VPN but you still have to trust the VPN provider. But ISPs have extraordinary amounts of metadata in almost every case anyway. In the UK ISPs are legally obliged to keep a list of websites that have been accessed.
Self-hosting is normally better than not self-hosting, and decentralised is normally better than centralised. But this is because of freedom much more than it is because of privacy. For privacy the best thing is to not use the internet at all.
so the benefit of Threema in this scenario over Whatsapp would only be the clients being open source, and how good that is depends on how much clients actually do
You have to trust the server with all your meta data. So it’s as good as whatsapp.

to be fair, the whatsapp apps aren’t open source, right?

No, but the data is end to end encrypted, allegedly
