Isn’t Signal still centralised? Why use it over Matrix? (genuine question)

Matrix leaks a ton of metadata and for normal users the clients are still very much in the sucking phase. Signal being centralized changes nothing about its security when the freaking servers can’t see anything about the messages. It literally is the most secure way to communicate out there, period.

Thanks; is leaking metadata just a consequence of the decentralized nature or is it something specific to how Matrix was made? Maybe I’ll try out Signal (I’ve been looking for some alternatives) but I don’t like how they’re based in America/5 Eyes, even if they are encrypted.

But yeah, that’s the thing, it doesn’t matter where it is based when there can’t be any information gleamed from it.
