I used to be on Signal, then they made a firm stances of no alternate clients, that I could accept. Then they were going in on crypto. I'd just stay away from it. Then they inserted a proprietary shim into their stack that they wouldn't allow to be audited, because it was SUPPOSEDLY to fight spammers. That was my last straw. Moved the family to Matrix and haven't looked back. Element is quite good imo. Especially for my family who aren't technically savy.
