You understand how the internet protocol works right. This argument has been going for a long time now. Yes, they gave up IP address because they couldn’t win in court. They’re like the only company who will fight tooth and nail for you in court but the feds ordered them to do so, so they had to comply. The messages were all end to end encrypted and other than what metadata was requested, they didn’t get much.

Edit: Additionally, if you use protonvpn, mullvad, or any no-log vpn, you would probably be immune to this.
