While Signal’s home base is the US, they are a non profit org that doesn’t operate in the same way as for-profit corporations. Also, Signal collects basically zero data so there’s no incentive to sell out, and who would want to buy them anyway when they have no data and the server and client are open source.
Matrix is great, but I wouldn’t compare it to Signal. I use both for very different purposes.

XMPP is more comparable to Signal, yes.
Signal does need (yes, need) a phone number, and most people only have one so that is identifiable info.
This puts it at mostly the same level as some competitors, including WhatsApp which is often advised against.
Signal will operate until Elon Musk decides that everyone has to use X to communicate.
