In the US, Cellebrite extractions are done under color of law; for the same reason, the police don’t get in trouble for forcing open locked doors while executing search warrants.

Are you sure that is the case 100% of the time?
Bars on my door keep out burglars as well as hinder police serving a warrant.
Even if Signal does deploy these files (no evidence thus far that they have deployed Cellebrite exploits, as their blog post was careful not to claim that), the vast majority of them (just like deadbolts) will not be used to hinder search warrants.
