That's a pretty selfish view. On the other hand such a serious backer means political clout and attention in case there are attempts to compromise it. E.g. Whispers Systems could quickly relocate to Estonia or Germany if US law becomes untenable.
It's not selfish to want to talk to your s.o. Sure, it's better if the CCP doesn't go around censoring reasonable communications, but given that they are, people are entitled to want whatever reasonable alternatives they can get.
Not so much selfish as realistic: now intelligence agencies like NSA can justify spending much more resources to exploit potential vulnerabilities in Signal, so—with Wikileaks in mind—it practically makes Signal less safe long-term.
