Ok, sure. But what do you propose? It's still a much better situation than what we have with Whatsapp. Is there something that the Signal Foundation could do to alleviate that concern you have? There's no technical solution in any technology for preventing the other side being compromised, as far as I can see.
That doesn't mean I blindly trust them, only that despite seeing potential for abuse I judge that they have more incentive to be telling the truth than not.
Also check the comment by user faitswulff where they mention how they have been subpoenaed "and could only supply account creation time and last connection time".

I don't know Matrix, but I can guarantee that it doesn't solve the problem of a compromised client obtaining the messages willingly sent to it.
