If a person is a member of a terrorist network - or friends with someone who is - the fact that a warrant could force Signal to expose that link could mean that a court is then more likely to approve increased surveillance of your (non-Signal) communications because of that link.
On the other hand if you are a woman on Tinder and using Signal to communicate with matches, this doesn't expose you to the person you have just matched with adding your number to their phone book, uploading it to LinkedIn and then finding where you work (which is what you can do with a phone number).
My feeling is this is a reasonable compromise, but it is important people understand what it does and doesn't protect you from.
