This is not correct. The trademark doesn't affect the copyright but you need both in order to publish binaries with the original name and logo in a store.

You need a copyright license to use the binary. You need a trademark license to use the trademark. See the firefox -> iceweasel kerfuffle

Link to where Signal added these terms? You've posted a variant of this claim several times on this post but as far as I can see Signal-Desktop is licensed under a pure AGPLv3 which definitely does not have such terms.
